validated. I have tried everything i could think of. It just reloads the
page.

Hello Babatunde,
Thank you for answering my question.
I have actually done that.
But Django throws and error whenever I I instantiate form/for_class to
ContactForm(request. POST).
It says it's expected only a single argumen. but two was provided.

Running Django Project Locally

[Lekan Wahab]

Good morning,
I was recently given  a django project to manage at work.
However, i noticed the project has neither a django-admin.py or a manage.py
file.
Is that normal?
If it is, how do i run the project on my local machine for testing purposes?

The file structure is something like this:
Project Name
app1
app2
app3
app4
app5
models.py
forms.py
__init__.py
urls.py
views.py
admin.py


Each app contains the following:
models.py
forms.py
__init__.py
urls.py
views.py
admin.py

Re: Running Django Project Locally

[Lekan Wahab]

Thanks for getting back to me.
​So, i just figured *manage.py* would also require the *settings.py* which
is missing now.
What do i do about that?

Re: Running Django Project Locally

[Lekan Wahab]

So,
I have been handed the other part of the project which now contains
everything except the manage.py file(which i have created).
Also, the project is quiet old  and some of the dependencies are either no
longer being managed or don't exist anymore.(unobase for an example).
As such, i was handed an eggs.zip containing the packages used by the
developer.
Now, the question is, how do i install the dependencies from the eggs.py
file?
I think its more of a python question than a django issue but i would still
appreciate whatever help i can get.



Lekan.

Maintaining old django code

[Lekan Wahab]

Good morning guys.
I was handed a project at work which was written as far back as 2012.
Quiet a lot of the packages used in the project are either no longer being
maintained.
Rebuilding the project from scratch is not option.
There are way too many moving parts and way too many apps to rebuild it.
Here are my questions:

1. In the scenario i am in, what would be the best approach to update this
project or at least get it set up locally?
2.  Quite a lot of changes have been made between django 1.4 (which was
originally used) and the current version(1.10), what would be the best
version for me to update the project to.
I mostly use 1.8 anyway.
3. Is there anyone who has or who is still using *unobase* here?

Help with FlatPages

[Lekan Wahab]

Good morning guys,

I'm trying to locally set up an existing  project on my machine.
While I've set up most of the project,  the part giving me a hard time are
the ones using flatpages.

Now,  everytime I access those,  I get a "No Flatpages matches the given
query. " error.

I've tried everything I can but with no luck.

However, there's a flatpages.json file in the project folder.

What could that be for?

Is there something I am supposed to do with that json file?

Hi kbman,
If you use PyCharm, you can easily read the sqlite3 file better with its
database integration.
Click on database.
Select from sources and then okay.

Re: HTML Flexbox CSS

[Lekan Wahab]

Hi,
In order to ease the work of making your changing your static files to the
right URL format in Django,  a friend of mine came up with a library called
*Staticfy* for it.

You can check it out on :
https://github.com/danidee10/Staticfy

It will really ease your work.

Re: One template for multiple views

[Lekan Wahab]

Hi,
I'm not sure I completely understand what you need but if I do,  I think
passing different contexts to the same template would help you achieve
that.

You could easily have something like :

def initial_view(request) :
   variableone = 'a'
   variabletwo = 'b'
   return response(yourtemplate, {'a':variableone, 'b' :variabletwo})

Then you can also have another view using the same template but with
different contexts.
Something like,

def final_view(request) :
   variableone = 'c'
   variabletwo = 'd'
   return response(yourtemplate, {'c':variableone, 'd' :variabletwo})

Also,  if you have a repetitive section in your template, you could just
write it once and use the {% include %} tag to use it in each of your other
templates.

I hope that helps.

Lekan.

created template and modify texts, but i don't like. Is it possible to use
same template for more views and only controll differences based on view,
which is template calling? For example, i need to show "Current month" or
"Previous month". I can put these texts into variable, but i hope there is
better way to controll directly in template.

Please, can you help me or point me to some good article? Thanks!

ListField, JSONField and DictField

[Lekan Wahab]

Hi guys,
This question just came to me this evening and I've really been thinking
about it.

Can someone explain to me why Django doesn't have ListField, JSONField or
DictField by default in its model Fields?

I mean,  these are obviously things that would ease a lot of work so why
aren't they available yet?

Lekan.
Python is the "most powerful language you can still read".

Re: Multiple Users

[Lekan Wahab]

##This is one approach.
You can have a single user profile and a number of other users tied to
the user profile via ForeignKey.


class UserProfile(models.Model):
user = models.ForeignKey(User)
#define general fields
class Freelancer(models.Model):
profile = models.ForeignKey(UserProfile)
#freelancer specific  fields

class Meta:
db_table = 'freelancer'
class Customers(models.Model):
profile = models.ForeignKey(UserProfile)
#customer specific fields

   class Meta:
db_table = 'customer'


Another approach(which i don't think is the best) would be to have a single
UserProfile but with a table that identifies the type of user you have.
Something like this:

class UserProfile(models.Model):
user = models.OneToOneField(User)
description = models.CharField(max_length=100, default='')
country = models.CharField(max_length=100, default='')
website = models.URLField(default='')
phone = models.IntegerField(default=0)

##The user type would be boolean and 0 by default. 0 could be a
freelancer and 1 a Customer or the other way round.
##So, based on the type of user you're creating, you could just
set a new value for user_type.
user_type = models.BooleanField(default=0)

###This method would come in handy if both users have exactly the same features.
###But I'd rather go with the first method.
