How to pass a variable to views from a template using href ?

[ratnadeep ray]

Hi all, 

My requirement is to pass a variable to the view from the template using 
href. 

For example, I have written the following line of code: 

SQL data


So using the above line, can we send the value "SQL" clicking on the link 
of "SQL data" to the method "execute" written in the views? If not, then 
what way can I do so? 

Thanks.

You need to configure apache correctly and set up your static url in django.

You can't really do that with Python - however - IF you want to go down

NEW TO DJANGO

[Madhav Nandan]

Dear Django fellas,

I'm new to Django here. I started learning and it's been a while and I'm
facing a lot of issues. Can somebody help me with *''how can I integrate a
payment system like PayPal to a link?''*
 Like I have a link, if someone clicks on that link that will redirect the
user to the payment page and there on the payment provider works.

I just need to get started and somebody can guide me here hopefully. I
don't' need code or so.

Help me here.

Best regards,

Re: How to pass a variable to views from a template using href ?

[Ignat Petrov]

You should be able to do that by using a relative path instead of the 
absolute "/execute". Just use something like href="{% url 'execute' 'SQL' 
%}. For this to work you need to name the url path as 'execute'. That way 
you'll pass the 'SQL' value to the endpoint.
Here is example from the polls tutorial: 
https://docs.djangoproject.com/en/3.0/intro/tutorial03/

Can't Fix the No Reverse Error in Ajax

[Ahmed Khairy]

I am trying to use Ajax to submit a like button, I believe everything is in 
order but I keep getting django.urls.exceptions.NoReverseMatch: Reverse for 
'like_post' with arguments '('',)' not found. 1 pattern(s) tried: 
['score/like/(?P[0-9]+)$']


I am not sure what is the reason. Need help to identify the error.


Here is the view


class PostDetailView(DetailView):
model = Post
template_name = "post_detail.html"

def get_context_data(self, *args, **kwargs):
context = super(PostDetailView, self).get_context_data()
stuff = get_object_or_404(Post, id=self.kwargs['pk'])
total_likes = stuff.total_likes()
liked = False
if stuff.likes.filter(id=self.request.user.id).exists():
liked = True
context["total_likes"] = total_likes
context["liked"] = liked
return context


def LikeView(request, pk):
# post = get_object_or_404(Post, id=request.POST.get('post_id'))
post = get_object_or_404(Post, id=request.POST.get('id'))
like = False
if post.likes.filter(id=request.user.id).exists():
post.likes.remove(request.user)
like = False
else:
post.likes.add(request.user)
like = True
context["total_likes"] = total_likes
context["liked"] = liked

if request.is_ajax:
html = render_to_string('like_section.html', context, request=
request)
return JsonResponse({'form': html})

Here is the url.py updated

urlpatterns = [
path('user/', UserPostListView.as_view(), name=
'user-posts'),
path('', PostListView.as_view(), name='score'),
path('who_we_Are/', who_we_are, name='who_we_are'),
path('/', PostDetailView.as_view(), name='post-detail'),
path('like/', LikeView, name='like_post'),
path('new/', PostCreateView.as_view(), name='post-create'),
path('/update/', PostUpdateView.as_view(), name='post-update'),
path('/delete/', PostDeleteView.as_view(), name='post-delete')
]

here is the template


{% csrf_token %}
 Likes: {{total_likes}}  
{% if user.is_authenticated %}
{% if liked %}
 Unlike 
{% else %}
 Like 
{% endif  %}
{% else %}
 Login to Like 
{% endif %}   
   

here is the ajax

https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js";>


$(document).ready(function(event){
$(document).on.('click','#like', function(event){
event.preventDefault();
$var pk= $(this).attr('value');
$.ajax({
type:'POST',
url:'{% url "score:like_post" post.pk %}',
data:{'id': pk, 'csrfmiddlewaretoken':'{{csrf_token}}'},
dataType:'json', 
success:function(response){
$('#like-section').html(response['form'])
console.log($('#like-section').html(response['form'
]));
},
error:function(rs, e){
console.log(rs.responseText);   
},
});
});
});

Re: PROBLEM WITH Multiple SETTINGS.PY FILE

[Jorge Gimeno]

I'm not sure why you're getting an exception.  I know the import mechanism
in Python 2 was a bit different, so I'm not sure if that's the issue or if
Django's import mechanism isn't finding your settings file.

I don't know if you have tried this, but I saw a blog post on using
multiple settings files.  Maybe it will help:
https://simpleisbetterthancomplex.com/tips/2017/07/03/django-tip-20-working-with-multiple-settings-modules.html

I hope this helps!

Re: Categories and shoe Subcategories according to the parent category.

[Antje Kazimiers]

you could have a field "parent" in your Model Category which is a
ForeignKey to Category itself, so Category is a self-referencing table.

Then in your first dropdown you only show those entries where parent is
None and in your second one where parent == accessories.

you need to get this right with your view which would be
show_child_categories where you pass the id of your parent and filter
for it in your view function.

hope that helps, antje

Re: PROBLEM WITH Multiple SETTINGS.PY FILE

[Mike Dewhirst]

I thought I'd go back and look at your original post. Your settings file 
looks a bit tricky.


I learned to deal with multiple settings files a long time ago so I 
don't know what current best practice is. Essentially, the way I do it 
is to have a complete base.py with all settings in a default state for 
security and production components. Then I have all my separate settings 
files ...


from base import *

... followed by the adjusted settings for that environment. Typically 
they will be production.py, staging.py and local.py


Then depending on the environment my wsgi.py imports settings.production 
or settings.mike-local or whatever.


It looks to me as though you are doing the opposite. Your wsgi.py 
imports a single settings file which has a massive if/elif block to 
import one of a multitude of other settings files each of which imports 
the equivalent of my base.py (your settings_common.py)


My mechanism has a single import statement while yours has at least two.

I think your wsgi.py should have the massive if/elif block to simply 
name the correct settings file (based on the host name) whenever the web 
server reloads.


It might reduce importing complexity somewhat and possibly solve the 
problem.


My settings arrangement is

base - all the settings as defaults
production - all the production settings no matter which host
staging - all the staging settings no matter which host
local - all the local settings including detecting the OS, setting DEBUG 
switching off security etc

local-mike - all my own settings including sqlite for faster testing
local-test - including postgreSQL for rigorous testing

I also needed to simulate environments. My mechanism is to rename the 
project directory and detect that in my settings.base.py like this ...


if deploy_dir == 'bis': # pragma: no cover
    PRODUCTION = "pq3"    # hostname
    DOMAIN = 'djfghdsgdlg.com'
    BRANDING = 'BIS'
    BRAND_URL = 'https://www.{0}/'.format(DOMAIN)
    ADMIN_URL = 'https://pay.{0}/admin'.format(DOMAIN)
    ALLOWED_HOSTS = [u'pay.{0}'.format(DOMAIN)]
    FUNCTION = 'invoice'
elif deploy_dir == 'cli': # pragma: no cover
    etc etc

I also wrote a couple of utilities which are called from dev versions of 
my settings files. They print out all settings which significantly 
change between hosts depending on which host I'm simulating.


In summary, I don't think I can help just by looking at the error - 
other than the obvious error being reported in a settings file - but I 
would definitely try and simplify the importing. And I do like to print 
out all the essential settings every time runserver reloads.


Good luck

M

I'm not sure why you're getting an exception.  I know the import

that's the issue or if Django's import mechanism isn't finding

I don't know if you have tried this, but I saw a blog post on
using multiple settings files.  Maybe it will help:

It is possible you need a top line in the file like this ...

from __future__ import absolute_import

I haven't been following this thread so someone may have

already.

Can Django (application itself) connect to MySQL via Kerberos/GSSAPI ticket instead of password?

[Edward Rose]

Hello - Does Django have any support for the web application itself being 
able to connect to MySQL using Kerberos Authentication / GSSAPI rather than 
a hard coded database user name and password?

I have searched around the web for a while and am still trying to find a 
way to get a Django web app itself to authenticate to a MySQL DB equipped 
with GSSAPI plugin via Kerberos. The Django app runs off Apache started in 
this way:

k5start -u user/server@domain -f /etc/krb5.keytab -- /usr/sbin/httpd 
-DFOREGROUND

The user/server user exists on the DB with adequate permissions. Moreover, 
on the command line this works and connects up fine:

k5start -u user/server@domain -f /etc/krb5.keytab -- mysql -u user/server

However, I've tried getting the web app to connect to the DB (the app 
itself, not worrying about the user authentication yet) about a million 
different ways. I verified the user running the web app is apache even when 
run started up the k5start way. Nonetheless any requests are met with this 
error:

(1105, 'Client GSSAPI error (major 851968, minor 0) : gss_init_sec_context - 
Unspecified GSS failure.  Minor code may provide more information. ')


The settings.py configuration for the database is as follows:

DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql', 
'NAME': 'my_database',
'USER': 'user/server@domain',
#'PASSWORD' : '',
'HOST': 'localhost', # Or an IP Address that your DB is hosted on
'PORT': '3306',
}
}



Server Specs:
Django version: 2.2.8
Python version: 3.6.8
OS version: RHEL 7.8 (Maipo)
MySQL version: 10.1.45-MariaDB MariaDB Server


I am thinking perhaps Django is just not designed to work this way? I did 
trace some of the code in the packages Django uses to connect to MySQL and 
it appears to be something along the lines of mysql_connect / the MySQL 
Connector C libraries or whatnot. And from what I saw a lot of the 
parameters the code uses following the MySQL website documentation but 
there was one parameter 'auth_plugin' or something like that, which did not 
seem to be implemented. Yet at the same time it would seem like getting 
Django to connect to the DB via kerberos would be a common problem? Again, 
this is a separate problem I'm trying to solve besides authenticating users 
to the website, rather I'm hoping to allow the app itself to authenticate 
to the database with kerb ticket, and had been hoping starting up apache in 
a kerberized way might let that happen. 

Any suggestions from people more Kerberos knowledgeable than I?

Mysql8.0以上的版本更改了加密规则，这可能需要你多研究一下遇到的问题。我记得需要修改Django框架中的一些源码。
