Is it possible to create website like Squarespace or Wix in django?

[Kakar]

Hello everyone! I am really a newbie in the django world, and it might be 
to much to ask now this question, but am just curious. So, is it possible 
to make websites like Squarespace or wix where the user can itself choose 
the template or customize it later on, and also that a programmer can 
change the the css too. Please comment your views. Thanks.

Authenticate users with both username and email

[Kakar Nyori]

I have extendted the *UserCreationForm* with email and other fields, so 
that I could authenticate a user with both its username and email.

forms.py:

> class UserCreationForm(UserCreationForm):
> class Meta:
> model = User
> fields = ('first_name', 'last_name', 'username', 'email',)


 
views.py:

def auth_view(request):
> username = request.POST.get('username','')
> password = request.POST.get('password','')
> user = auth.authenticate(username=username, password=password)
> if user is not None:
> auth.login(request, user)
> return HttpResponseRedirect('/')
> elif:
> user = auth.authenticate(email=username, password=password)
> if user is not None:
> auth.login(request, user)
> return HttpResponseRedirect('/')
> else:
> return HttpResponseRedirect('/accounts/invalid_login')


html:


> {%csrf_token%}
> Email or Username:
> 
> Password:
> 
> 
> 



In the views I tried giving both the *username* and *email *as input from 
the form as *name*, and check to see if username and password authenticate. 
If not then check whether email and password authenticate. But its not 
working. How do I solve this problem? Please kindly help me. Thank you.

Handle multiple modelforms in one html form

[Kakar Nyori]

A user will have photos which will be related with their specific album.

So this was the model for that:

class Album(models.Model):
> user = models.ForeignKey(User)
> title = models.CharField(max_length=200)
> pub_date = models.DateTimeField(auto_now_add=True, auto_now=False)
> update = models.DateTimeField(auto_now_add=False, auto_now=True)
> class Photo(models.Model):
> photo_privacy = models.CharField(max_length=1,choices=PRIVACY, 
> default='F')
> user = models.ForeignKey(User)
> caption = models.TextField()
> image = models.ImageField(upload_to=get_upload_file_name)
> pub_date = models.DateTimeField(auto_now_add=True, auto_now=False)



Views.py:

def create_album(request, user_name):
> user = User.objects.get(username=unquote(user_name))
> if request.method=='POST':
> pform = AlbumPhotoForm(request.POST, request.FILES)
> aform = AlbumForm(request.POST)
> p_valid = pform.is_valid()
> a_valid = aform.is_valid()
> if p_valid and a_valid:
> photo = pform.save(commit=False)
> album = aform.save(commit=False)
> photo.user = user
> album.user = user
> album.save()
> photo.album = album
> photo.save()
> return HttpResponseRedirect('/'+user.username+'/photos')
> else:
> return render(request, 'create_album.html',{
> 'pform':pform,
> 'aform':aform
> })
> else:
> pform = AlbumPhotoForm()
> aform = AlbumForm()
> return render(request, 'create_album.html', {
> 'pform':pform,
> 'aform':aform
> })


And the form:

 enctype="multipart/form-data">
> {% csrf_token %}
> {{ aform.as_p }}
> {{ pform.as_p }}
> 
> 


This works fine if I only have to upload one file (photo) with that form.

However what I want to do is, show minimum of three input for uploading 
photos to the new album:

 enctype="multipart/form-data">
> {% csrf_token %}
> {{ aform.as_p }}
> {{ pform.as_p }}
> {{ pform.as_p }}
> {{ pform.as_p }}
> 
> 


When doing so, only the last *pform* is gets saved. And the other two 
*pform*s are ignored. How do I get to save all the three forms of photo (
*pforms*) accordingly?

Or is there any other way around? Your help will be much appreciated! Thank 
you.

amazon s3 and django - Allow only the users from my website and not the anonymous users

[Kakar Nyori]

I am using amazon s3 to store uploaded user images. My problems are:

- If I permit or grantee for me, I cannot upload or download the contents.
- If I permit or grantee for everyone, all the users and (especially) 
anonymous users will be able to see the contents, which I don't want.

So, my question is, what do I do so that only the users from my website can 
upload, download and delete the content? 

In that I have conditions that:

 1. Only the users (user1, user2, user3, ...) who are following the user
(user0) can download/view the content?
 2. Only the user who uploaded the view can delete the content.

models.py:

*def get_upload_file_name(instance, filename):*
*return "uploaded_files/%s_%s" %(str(time()).replace('.','_'), 
filename)*

*PRIVACY = (*
*('H','Hide'),*
*('F','Followers'),*
*('A','All'),*
*)*

*class Status(models.Model):*
*body = models.TextField(max_length=200)*
*image = models.ImageField(blank=True, null=True, 
upload_to=get_upload_file_name)*
*privacy = models.CharField(max_length=1,choices=PRIVACY, 
default='F')*
*pub_date = models.DateTimeField(auto_now_add=True, auto_now=False)*
*user = models.ForeignKey(User)*

settings.py:

* DEFAULT_FILE_STORAGE = 'storages.backends.s3boto.S3BotoStorage'*

* AWS_ACCESS_KEY_ID = 'AKIAJQWEN46SZLYWFDMMA'*

* AWS_SECRET_ACCESS_KEY = '2COjFM30gC+rty571E8eNSDYnTdV4cE3aEd1iFTH'*

* AWS_STORAGE_BUCKET_NAME = 'yesme'*

Thank you.

no module in error log django-1.3.7

[Kakar Nyori]

Hello,
I am trying to run a python app in pythonanywhere.com. If I run the project

no module named appname.

What went wrong?

Re: broken image on my django production site. Why is it?

I think, you should add "static"/ in your html:



Or else change your directory settings.

Re: Uploadfile form and CSS Style

Re: Uploadfile form and CSS Style

[Kakar Nyori]

Hello Russo,

You need to select the input button in the css. Something like this:

input[type=submit] {
background-color: transparent;
border:none;
cursor:pointer;
background-color:blue;
color:white;
}

Note that this will select every "submit" type button in your html. So if
you don't want all of them to be like the above, then you need to provide
the ID and and then select the submit button. You can check it by the *inspect
element tool, *as Collin has described. Or you can manually do it in your
forms as Donarb has described.

Hope this will make some sense.

Cheers!

Review needed

[Kakar Nyori]

Hello,
This may be long, but I really need your help. I have a class *Asset*, 
which is the *base class* of another *classes *(like *Photo, Question, 
Video etc.*) Basically its a *Multiple Table Inheritance*. I need this to 
get all the post or all the *objects* of the user. And it does what I want. 
But I saw that, many were against *Multiple Table Inheritance, *or if not 
they discouraged MTI. So, I really need to know that, *how much will it 
matter*? Or is there any other way to achieve it. To get all the objects of 
a *User*? Please help me decide what to do. If I am not clear, please ask 
me. I will really appreciate if anyone would guide me through this.

Thank you.

*This are my models:*


class Asset(models.Model):
user = models.ForeignKey(User, related_name = "user_objects")

Create objects using a start date, an end date and time list

[Kakar Nyori]

I have an Event model, and each event will have different shows.

class Event(models.Model):
title = models.CharField(max_length=200)

class Show(models.Model):
event = models.ForeignKey(Event, on_delete=models.CASCADE)
date_time = models.DateTimeField(unique=True)

class Ticket(models.Model):
show = models.ForeignKey(Show)
seat = models.ForeignKey(Seat)

class Meta:
unique_together = ('show', 'seat')

I need to create shows based on the start date and end date provide by the 
user. Suppose this is a JSON post:

{
"event_id": 1,
"start_date": "2018-02-16",
"end_date": "2018-02-20",
"time_list": ["11:00 AM", "8:00 PM"]
}

>From the above JSON example, I need to create Show starting like this:

# Start with the start_date as the date, and for each time from the 
time_list
Show.objects.create(
event = 1,
date_time = datetime.strptime('2018-02-16 11:00 AM', "%Y-%m-%d 
%I:%M %p")
)
Show.objects.create(
event = 1,
date_time = datetime.strptime('2018-02-16 8:00 PM', "%Y-%m-%d %I:%M 
%p")
)
# Next date after the start_date, i.e., 16+1 = 17
Show.objects.create(
event = 1,
date_time = datetime.strptime('2018-02-17 8:00 PM', "%Y-%m-%d %I:%M 
%p")
)
.
.
.
# Create Show objects till the end_date and for each time from the 
time_list
Show.objects.create(
event = 1,
date_time = datetime.strptime('2018-02-20 8:00 PM', "%Y-%m-%d %I:%M 
%p")
)

Right now this is how I am creating Show objects:

def create_show_by_datetime(self, request):
event_id = request.data['event_id']
start_date = request.data['start_date']
end_date = request.data['end_date']
time_list = request.data['time_list']

format = '%Y-%m-%d'
delta_days = datetime.strptime(end_date, format).date() - 
datetime.strptime(start_date, format).date()
delta_days = delta_days.days + 1

for i in range(delta_days):
day = datetime.strptime(start_date, format) + timedelta(days=i)
for i in range(len(time_list)):
hrs = datetime.strptime(time_list[i], "%I:%M %p").hour
mins = datetime.strptime(time_list[i], "%I:%M %p").minute
event = Event.objects.get(id=event_id)
dt = day + timedelta(hours=hrs, minutes=mins)
show = Show.objects.create(
event=event,
date_time=dt
)

But I am really hoping there's much more elegant way than how I am doing. I 
am using python 3, django 2 and django rest frameowork. Could you please 
help me?

Thank you

Understanding django channels persistant data

[Kakar Nyori]

I am trying to grasp the concept of persistant data in django channels
.
I have searched the reference and other parts but didn't clear my
confusion. I would really appreciate if you help me understand better.

consumers.py:

@channel_sessiondef ws_connect(message):
# Work out room name from path (ignore slashes)
room = message.content['path'].strip("/")
# Save room in session and add us to the group
message.channel_session['room'] = room
Group("chat-%s" % room).add(message.reply_channel)

Q.1 In the above line message.channel_session['room'], is the room another
property of the message? Like it tells which session the message belongs to?

@channel_sessiondef ws_message(message):
Group("chat-%s" % message.channel_session['room']).send({
"text": message['text'],
})

Q2. In the line Group("chat-%s" % message.channel_session['room']).send({,
why are we not using the *room* variable like in the ws_connect() function,
but instead we are using the channels_session?

@channel_sessiondef ws_disconnect(message):
Group("chat-%s" %
message.channel_session['room']).discard(message.reply_channel)

Q3. Same like above, why are we not using the *room* variable to discard
from the group? Also is it not neccesary to remove the room from the
session?

Re: Understanding django channels persistant data

[Kakar Nyori]

Wow, from the creator himself! Thank you.
>
>
Just so we're clear, *message.channel_session['key']* is the same as 
*request.session['key']*, did I get you correctly?

And there's just this another confusion, why can't we us *"text": 
message.content['text']*, but instead its *"text": message['text']*?

Thank you

Re: Understanding django channels persistant data

Hi,

Yes that was it. Although I was getting this error:
*ERROR - worker - Error processing message with consumer 
myproject.consumers.ws_message:*

But this was corrected after the *enforce_ordering *was added into the 
consumer function. Thank you so much for your help and for introducing such 
a great tool for us.

Re: What is the best combination of components when installing Django on Windows 10?

[Kakar Nyori]

Hi,

I use windows, and I too was confused about these things. The best 
recommendation I got was to use *Vagrant, *and to this day I use it. 

*"Vagrant is a tool for building complete development environments."*

Basically you select an environment like ubuntu OS (called vagrant box), 
and then you add it as your vagrant environment. With this as your local 
development you get many benefits:

1. Since you will eventually be using OS like ubuntu in production, you get 
the same environment for the development as well.
2. You can play around with the environment.
3. And since you have the production like environment, you can basically do 
all the stuff you would do in production. Like you want gunicorn, ok, 
install it in your vagrant environment and use it.
4. You can administer and practice in the machine like you would do for the 
production.
5. You can have the same exact configuration that is in your production 
machine.

Hope this will be helpful to you as it was for me. And again, this may not 
be the best practice for someone else.

Cheers!

Kakar.

Migrating from django user model to a custom user model

[Kakar Nyori]

I am following these two references (one 
 and two 
)
 
to have a custom user model in order to authenticate via email and also to 
add an extra field to it.


class User(AbstractBaseUser, PermissionsMixin):
email = models.EmailField(
unique=True,
max_length=254,
)
mobile_number = models.IntegerField(unique=True)
is_active = models.BooleanField(default=True)
is_admin = models.BooleanField(default=False)

objects = UserManager()
...
...
class Meta:
db_table = 'auth_user'
...
...


As you can see, I have added the db_table='auth_user' into the Meta fields 
of the class. Also, I have included AUTH_USER_MODEL = 'accounts.User' and 
the User model app (i.e., accounts) into the INSTALLED_APPS in settings.py. 
Further more, I deleted the migrations folder from the app.


Then tried migrating:

$ python manage.py makemigrations accountsMigrations for 'accounts':
  accounts/migrations/0001_initial.py:
- Create model User

$ python manage.py migrate accounts

Which gives me an error:

django.db.migrations.exceptions.InconsistentMigrationHistory: Migration 
admin.0001_initial is applied before its dependency accounts.0001_initial 
on database 'default'.

How can I migrate from the existing django user model into a custom user 
model? Could you guys please help me out.


Thank you

How to django with jquery-mobile

[Kakar Nyori]

Django provides many features for the template (extends, block content
etc.) I am just learning jquery mobile, but so far when using jquery
mobile, there's just one actual html page and inside it we have to create a
page (data-role="page"). So, how can we utilize the django's templating
features with jquery mobile? Or how to django with jquery mobile? Please
help me understand this concept. Thank you.

I'm practicing from a book Begining django e-commerce and m stuck in one
place. My project name is ecomstore, and in it i have two app, one is
preview and the other is catalog. In my preview app, there's just html in
the templates dir, and thats not the problem, because the result was fine
when i ran the server. And then i made a new app, catalog. It has two
models, Category and Product. Then to register it with the admin, i made
one admin.py file. And there i imported those two module by:
from django.contrib import admin
from django.ecomstore.catalog.models import Category, Product
...and some other forms related import.
Then when i run the server, i get an Import error: No module named
catalog.models.

Oh..m sorry. I mistyped, it was not django.ecomstore.catalog.models, but
just, ecomstore.catalog.models import Category, Product. N in the catalog
dir, it has __init__.py file, so should have done the problem. N m using
sqlite3 so i dnt need adapters too. Pls help.

Re: no module name error

ecomstore is the project name. And within it, it has another ecomstore,
which has the __init__.py, settings.py, urls.py and wsgi.py. And yes
catalog too has the __init__.py file in it, as it was created by the
startapp command. The error says, import error: no module named
catalog.models in admin.py line 2, which is, from ecomstore.catalog.models
import Category Product.

Ok i removed ecomstore from,
from ecomstore.catalog.models import Product, Category
to
from catalog.models import Product, Category
And i think it worked fine. But now again it gives an error:
ImproperlyConfigured at/catalog - 'ProductAdmin.exclude' refers to field
'created_at' that is missing from the form.

CSRF verification failed

[Kakar Arunachal Service]

Hello!
I am getting CSRF verification failed error, even after i added {%
csrf_token %} tag in the html file.

Here's my html file:

{% extends "base.html" %}
{% block title %} User Registration {% endblock %}
{% block head %} User Registration {% endblock %}
{% block content %}

{% csrf_token %}
{{ form.as_p }}


{% endblock %}

and my views.py:

def register_page(request):
if request.method == 'POST':
form = RegisrationForm(request.POST)
if form.is_valid():
user = User.objects.create_user(
username = form.cleaned_data['username'],
password = form.cleaned_data['password1'],
email = form.cleaned_data['email']
)
return HttpResponseRedirect('/')
else:
form = RegisrationForm()
variables = RequestContext(request, {
'form': form
})
return render_to_response('registration/register.html',
variables)
else:
return render_to_response('registration/register.html')

Where am i doing wrong???

form.errors

[Kakar Arunachal Service]

Hi,
I am learning Django from an old Django version book, and i am stuck with a
problem regarding forms. When i render forms, i get the registration right,
but if its incorrect, it does not show the error msg in the html. I tried
{{form.errors}}, but couldn't fix he problem. Please guide me.
Thank you.

This is my forms.py:

from django import forms
import re
from django.contrib.auth.models import User
from django.core.exceptions import ObjectDoesNotExist


class RegistrationForm(forms.Form):
username = forms.CharField(label='Username', max_length=30)
email = forms.EmailField(label="Email",)
password1 = forms.CharField(
label='Password',
widget=forms.PasswordInput()
)
password2 = forms.CharField(
label = 'Password (Again)',
widget=forms.PasswordInput()
)

def clean_password2(self):
if 'password1' in self.cleaned_data:
password1 = self.cleaned_data['password1']
password2 = self.cleaned_data['password2']
if password1 == password2:
return password2
raise forms.ValidationError('Password do not match.')

def clean_username(self):
username = self.cleaned_data['username']
if not re.search(r'^\w+$', username):
raise forms.ValidationError('Username can only contain
alphanumeric characters and the underscore.')
try:
User.objects.get(username=username)
except ObjectDoesNotExist:
return username
raise forms.ValidationError('Username is already taken.')

def clean_email(self):
if 'email' in self.cleaned_data:
email = self.cleaned_data['email']
try:
User.objects.get(email=email)
except ObjectDoesNotExist:
return email
raise forms.ValidationError('Email is already taken.')

And this is my views.py:

def register_page(request):
if request.method == 'POST':
form = RegistrationForm(request.POST)
if form.is_valid():
user = User.objects.create_user(
username=form.cleaned_data['username'],
email=form.cleaned_data['email'],
password=form.cleaned_data['password1']
)
return HttpResponseRedirect('/register/success/')
else:
form = RegistrationForm()
variables = RequestContext(request,{
'form':form
})
return
render_to_response('registration/register.html',variables)
else:
form = RegistrationForm()
variables = RequestContext(request,{
'form':form
})
return render_to_response('registration/register.html',variables)

And my register.html:

{% extends "base.html" %}
{% block title %}User Registration{% endblock %}
{% block head %}User Registration{% endblock %}
{% block content %}

{% csrf_token %}
{{form.as_p}}


{% endblock %}

Re: form.errors

[Kakar Arunachal Service]

Okay! That did solved the problem. Thank you! Here's my new view.py:

def register_page(request):
if request.method == 'POST':
form = RegistrationForm(request.POST)
if form.is_valid():
user = User.objects.create_user(
username=form.cleaned_data['username'],
email=form.cleaned_data['email'],
password=form.cleaned_data['password1']
)
return HttpResponseRedirect('/register/success/')

else:
form = RegistrationForm()
variables = RequestContext(request,{
'form':form
})
return render_to_response('registration/register.html',variables)

I am just a noob with these things. I understood why the first instance
didn't worked, but can u please explain to me about the indentation part
(variables and return)? I am little bit puzzled in here. And don't the
second 'if' require an else?
Thanks again!

Re: form.errors

[Kakar Arunachal Service]

Okay. Thank you so very much! Just one last question, just to know that i
got it right. So, variables and return are not part of the else clause, and
that they return the errors of the last form post. Did i got it right?

'SimpleLazyObject'

[Kakar Arunachal Service]

I've got a TypeError:

int() argument must be a string or a number, not 'SimpleLazyObject'


Here's my view:

def bookmark_save_page(request):
if request.method == 'POST':
form = BookmarkSaveForm(request.POST)
if form.is_valid():
# Create or get link.
link, dummy = Link.objects.get_or_create(
url=form.cleaned_data['url']
)
# Create or get bookmarks.
bookmark, created = Bookmark.objects.get_or_create(
user = request.user,
link = link
)
# Update bookmark title.
bookmark.title = form.cleaned_data['title']
# If the bookmark is being updated, clear old tag list.
if not created:
bookmark.tag_set.clear()
# Create new tag list.
tag_names = form.cleaned_data['tags'].split()
for tag_name in tag_names:
tag, dummy = Tag.objects.get_or_create(name=tag_name)
bookmark.tag_set.add(tag)
# Save bookmark to database.
bookmark.save()
return HttpResponseRedirect(

else:
form = BookmarkSaveForm()

variables = RequestContext(request, {'form': form})
return render_to_response('bookmark_save.html',variables)

I really don't know what's going on here. Please guide me.

Display error message

[Kakar Arunachal Service]

Hi,
I have a site, that has a submit form, but one must be logged in for that.
And if the user is not logged in, it redirects it to the login page. And
this all fine. My question is, what do I do to display the error message,
"You must be logged to submit.", if the user is not logged in and tries to
submit the form, but has to display the normal login page if not.
Thank you.

didnt understood much in the link you gave me. Its that, suppose I included
it where users can post, will each post require another css, or something
else. Please explain.
