Re: How to over ride the get context data method in view

2020-05-13 Thread Andréas Kühne

Hi,

We can't solve all of your problems for you :) But that being said - in the
get_context_data you don't have a parameter for the request, however in all
CBV you get the request as a variable on the CBV itself - so change:

post.is_liked = post.likes.filter(user=request.user).exists()

To:


post.is_liked = post.likes.filter(user=self.request.user).exists()

Regards,

Andréas

 Hi again,

 Bare with me - this is just written in this email - so:

 1. Your listview is paginated by 5, so it will only show 5 posts -
 that's good for this exercise and how I would solve it.
 2. Rewrite your get_context_data method to iterate over the posts:
 def get_context_data(self, **kwargs):
 context_data = super(PostListView,
 self).get_context_data(**kwargs)
 for post in context_data['posts']:
 post.is_liked = post.likes.filter(user=user).exists()
 return context

 So now your page should show. In the page template:

 % extends "base.html"%} {% block content %} {% for post in posts %}
 {{post.title}}
 
   {% csrf_token 
 %} {% if is_like %}   >>> type="submit">Unlike

   {% else %}
   Like
   {% endif %}{% endfor %} {% endblock content %}

 Something like this should give you the functionality you want -
 however it's still a bit cumbersome.

 Regards,

 Andréas

Inserting data from a text file is not working for Postgres database

2020-05-13 Thread Ram

 Hi,

We are trying to insert the data from a text file '*some_category_list.txt*''
into a table in Postgres database using the highlighted query in our
functions.py

file = open(str(a)+'_category_list.txt', 'r')
> file_content = file.read()
> print(file_content)
> file.close()
> from django.db import connection
> cursor = connection.cursor()
> *query = "COPY pages_rim_ls_categories FROM '{0}_category_list.txt' WITH
> DELIMITER AS '|'".format(str(a)) *
> cursor.execute(query)
>
>
and we are getting this error

django.db.utils.OperationalError: could not open file
> "some_category_list.txt" for reading: No such file or directory
>


> HINT: COPY FROM instructs the PostgreSQL server process to read a file.
> You may want a client-side facility such as psql's \copy.
>

Note: We used below query in the past using MySQL and it worked fine with
that.

query = "LOAD DATA LOCAL INFILE '*some_category_list.txt'* INTO TABLE
> pages_rim_ls_categories FIELDS TERMINATED BY '|' LINES TERMINATED BY '\n' "
>

We are wondering what we are missing. Could someone help here to verify
this?

dude the error is staring at you. have you read the logs? just update the

Gunicorn-wsgi-nginx-postgresql-django linode hosting

2020-05-13 Thread Tobi DEGNON

Hi I need help, I'm hosting a django app on linode, the app is running on 
Ubuntu 18.04 LTS with gunicorn, nginx a postgresql database, and I'm using 
let's encrypt for SSL certificate, the issue is when I fill a form (login 
or signup) I get a timeout error but I don't have that issue on the admin 
site, when I try login to the admin it works just fine, and I don't have 
the timeout error on my local machine on the app, this is like the fourth 
time I'm setting up the whole thing with a different Ubuntu version each 
time, and I'm having the exact same issue, I made some research and then 
update timeout for nginx and gunicorn to 300, but it doesn't work, this is 
the first time I'm hosting a django app on a Linux server and I'm having 
the worst time of my life, this is a full traceback of the error 
https://gist.github.com/Tobi-De/38a3badf79bdf9fb0fe45cb0322d6293 , dont't 
let that EmailAddress.DoesNotExist exception full you, it does exist, I 
create the account with the createsuperuser command.

 That is really strange

 3. you are trying to get the absolut url for your post, but aren't

from django.contrib import admin
from django.urls import path, include 
from django.views.generic.base import TemplateView 
from django.contrib.auth import views as auth_views

urlpatterns = [
path('admin/', admin.site.urls),
path('accounts/', include('accounts.urls')), 
#path('users/', include('django.contrib.auth.urls')), 
path('accounts/login/', auth_views.LoginView.as_view(template_name=
'registration/login.html'), name='login'),
path('accounts/logout/', auth_views.LogoutView.as_view(template_name=
'logout.html'), name='logout'),
path('', include('blog.urls')),
path('password-reset/', 
 auth_views.PasswordResetView.as_view

Re: How to over ride the get context data method in view

2020-05-13 Thread Ahmed Khairy

Hi There, 

I have rewritten the get_context_data method to be like this but I am 
getting name 'user' is not defined:


class PostListView(ListView):
model = Post
template_name = "score.html"
ordering = ['-date_posted']
context_object_name = 'posts'
paginate_by = 5

def get_context_data(self, **kwargs):
context_data = super(PostListView, self).get_context_data(**kwargs)
for post in context_data['posts']:
post.is_liked = post.likes.filter(user=user).exists() <- 
name 'user' is not defined
return context

I am also using this template just for testing till fix the issue 

Thank you Andreas with me

 I am currently trying to create a like button for my posts in Django

 I have reached to the part where I can add a like but I am facing 
 difficulty writing the code related to the view which linking the 
 PostListView if there is user who liked it or not. I am getting an error: 
 page Error 404 although everything is correct


 this the views: 


 class PostListView(ListView):
 model = Post
 template_name = "score.html"
 ordering = ['-date_posted']
 context_object_name = 'posts'
 queryset = Post.objects.filter(admin_approved=True)
 paginate_by = 5

 def get_context_data(self, **kwargs):
 post = get_object_or_404(Post, id=self.request.POST.get(
 'post_id'))
 context = super(PostListView, self).get_context_data(**kwargs)
 context['posts'][0].likes.filter(id=self.request.user.id).
 exists()
 is_liked = False
 if post.likes.filter(id=self.request.user.id).exists():
 is_liked = True
 context = {'post': post,
'is_like': is_liked,
}
 return context



 def like_post(request):
 post = get_object_or_404(Post, id=request.POST.get('post_id'))
 is_liked = False
 if post.likes.filter(id=request.user.id).exists():
 posts.likes.remove(request.user)
 is_liked = False

 else:
 post.likes.add(request.user)
 is_liked = True

 return HttpResponseRedirect(post.get_absolute_url())


 This is the model 


 class Post(models.Model):
 designer = models.ForeignKey(User, on_delete=models.CASCADE)
 title = models.CharField(max_length=100)
 date_posted = models.DateTimeField(default=timezone.now)
 likes = models.ManyToManyField(User, blank=True, related_name='likes')

 def __str__(self):
 return self.title

 Here is the

 path('like/', like_post, name='like_post'),

 here is the template: 

 {% extends "base.html"%} {% block content %} {% for post in posts %}
 {{post.title}}
 
   {% csrf_token %} {% if is_like %}
   
   Unlike
   {% else %}
   Like
   {% endif %}Likes 

 {% endfor %} {% endblock content

Re: How to over ride the get context data method in view

2020-05-13 Thread Andréas Kühne

Hi again,

Bare with me - this is just written in this email - so:

1. Your listview is paginated by 5, so it will only show 5 posts - that's
good for this exercise and how I would solve it.
2. Rewrite your get_context_data method to iterate over the posts:
def get_context_data(self, **kwargs):
context_data = super(PostListView, self).get_context_data(**kwargs)
for post in context_data['posts']:
post.is_liked = post.likes.filter(user=user).exists()
return context

So now your page should show. In the page template:

% extends "base.html"%} {% block content %} {% for post in posts %}
{{post.title}}

  {%
csrf_token %} {% if is_like %}   Unlike

  {% else %}
  Like
  {% endif %}{% endfor %} {% endblock content %}

Something like this should give you the functionality you want - however
it's still a bit cumbersome.

Regards,

Andréas

Re: Can I use a JS Framework to display small JS tasks in a Django project?

2020-05-13 Thread Derek

Its not clear why you need JS at all. The app can load content from 
directories on the server side (back-end) and write these to a DB.  Django 
could then load these from the DB and show in the normal way.  Page 
generation can be done via normal views (Django/Python code).

(PS Both react and angular are not "new" - each are over 6 years old; more 
than 2 generations of computer science students...)

Viewing available functions and variables

2020-05-13 Thread Clive Bruton

I am using django-allauth for a user registration/log-in system. I  
have this working, however, as a general question, I would like to  
understand how one can view the functions/variables available on a  
given template.


For example I see that in some templates these are included:

{% user_display confirmation.email_address.user as user_display %}

{{ emailaddress.email }}

But I cannot, for example, access these in templates used for sending  
email.


Hope that is clear.

Re: help with my signup api

in your code data is json.dumps(request.data), which is a string
representation of the json dictionary

so data is a str and then you are trying to do item assignment to it

Oh yes, we all love javascript:

Seriously though, javascript has nothing to do with using static CSS in 
django templates.

Use {% include %} (https://docs.djangoproject.com/en/3.0/ref/ 
templates/builtins/#include) in your HTML template files for an  
embedded style sheet, or just use a link in the head of your template  
to serve the .css from the "static" folder (or other remote server  
location).

Re: How to over ride the get context data method in view

2020-05-13 Thread Andréas Kühne

Hi,

There are a couple of errors in your code:

1. You are using a ListView and then trying to get an individual post? That
is really strange
2. In your get_context_data method - you first get the context data, update
it and then you set it to a new dict, so everything is reset in the dict.
3. you are trying to get the absolut url for your post, but aren't showing
any post detail view.

Regards,

Andréas
