Re: Trying to print data containing a space in html

[Asad Jibran Ahmed]

Can you try moving the templatetags directory to be underneath the webpage
directory. I think that templatetags should be a part of an app.

Right now your templatetags are under the mysite folder, which if I'm not
wrong isn't considered an app.

Re: Help with runserver

[Asad Jibran Ahmed]

Do you have debugging turned on (DEBUG=True in settings.py) in Django? If
you do, you should see a pretty detailed stack trace and not just this.
Also, in the console you should see a stack trace with the details of the
error. Do you see those?

Re: Methods in Models

[Asad Jibran Ahmed]

Any method that works *only* with the model data and is used in multiple
places in the application should be a part of the model.

Next, if you have functions that operate on multiple pieces of data (or
more than 1 model instances) you should put them in the view where they are
used. But if these functions are needed from multiple views, then
personally I create a helper class to hold them, and the helper class is
outside the view and model files.

Of course in the end, none of these are hard and fast rules. Just go with
whatever you feel is more maintainable, and use these as general guidelines.

Re: Multiple Types of Account with Abstract User

[Asad Jibran Ahmed]

In that case I suggest you create multiple models, one for each type of
user. For example, you could have a SupplierProfile, DesignerProfile, etc...

The reason I suggest multiple profile models, instead of just one model
with a configurable account type field, is that I assume each of these user
types will have it's own data. For example the SupplierProfile might need a
bank account details field, whereas a designer probably does not.

So create multiple models, named similar to SupplierProfile,
DesignerProfile, etc and have each of those link to the Django user model
via a OneToOne key. This is similar to what you're doing with your
UserDetails models.

Hope that helps.

Re: Multiple Types of Account with Abstract User

[Asad Jibran Ahmed]

Did you change the AUTH_USER_MODEL setting *after *you had already run python
manage.py migrate once (or more) before? From the error I guess what's
happening is that you already have a User model in place. It was probably
created when you first ran Django migrations without specifying a custom
user model.

If that is the case, and you *really *want a custom user model, you'll have
to ensure that the user model is the first model create in your app. For
details look at the warning given at
https://docs.djangoproject.com/en/1.10/topics/auth/customizing/#substituting-a-custom-user-model
.

>From what I'm seeing of your models, you only seem to want to add extra
fields to each user. You can also do that by just pointing your UserDetails
model to the existing django.contrib.auth.models.User model, and adding the
type information in your UserDetails model instead. That might work for
you. Otherwise you'll have to remove your existing database and run
migrations from start.

Re: Compiling/packing Django to one binary

[Asad Jibran Ahmed]

Hi,
 While I haven't personally dealt with such a situation with my Django
code, I have worked with people who had this issue (un-deterministic
production servers). They used Docker to solve this issue. Essentially
you're looking for deterministic deploys, and Docker is the first thing
that jumps to my mind for something like this.

Is that a possibility that you can consider? If not, then I'm sure there
will be better answers to your question from other people in this group.

Re: How to use Django forms for surveys

[Asad Jibran Ahmed]

Hi,
 This is a complicated question and I'll do my best to answer it well, but
please forgive me if I miss somethings or say something inaccurate. I had a
similar project a while back and I did think about a possible solution,
something that might be of use to you.

If you want to use something pre-built, I suggest you take a look at
https://github.com/eldest-daughter/ed-questionnaire.

If you want something custom, read on.

Firstly, I'd present each question to the user on a separate page. I'd have
one Django view called QuestionView. I'd have a URL config similar to this:

url(r'^question/(?P(\d+))/$', QuestionView.as_view(), name='question')

Next I would come up with a data structure to hold the form configuration.
I don't mean a data structure like the ones you see in CS courses (trees,
maps, lists, etc). I mean a way to structure your data in a meaningful way.
For the scenario you describe, something like this might be a good starting
point:

QUESTIONS = [
 {
  "id": 1,
  "question": "Are you a programmer?",
  "options": ["No", "Yes"]
 },

 {
  "id": 2,
  "question": "Which operating system do you use?",
  "options": ["Windows", "Linux", "macOS"]
 },

 {
 "id": 3,
  "question": "Which editor do you use for writing code?",
  "show_if": {"question_id": 1, "answer": "Yes"}
  "options": ["Vim", "Emacs", "Sublime Text", "Other"]
 }
]

In this scenario, question id 3 is only shown if the user selected *Yes*
for question 1. Which means that you'll need to keep track of the answers
the user has already taken. Using the session storage for that is one good
option.

So each request to the Django app returns a page with a simple HTML page
with just one form. The form only has the widgets for the question being
answered. The view would take a look at the question it has to present, and
then generate a dynamic form based on that. Check out this post for a good
description of how to generate dynamic forms:
https://jacobian.org/writing/dynamic-form-generation/.

For question 1 in this case, the page would have a form with just 2 radio
buttons. When the user submits that form, you'll save their answer
somewhere (may the session storage) and then redirect the user to the URL
for the next question. To keep it simple, *always* redirect the user to the
next question.

Now comes the conditional logic of whether the user has to answer the
question or not. Let's say the user selected *No *for question 1, then
answered question 2 and was redirected to the URL for question 3. At this
point, your view looks at the config for question 3. The config says to
show this question only if the answer to question 1 was *Yes*. You check
the session storage and see that the user answered *No* for the first
question. So the user shouldn't have to answer this question. You simply
redirect the user to question 4, and this entire logic is checked again.

Of course this is only the starting point. An application like this is
going to get complicated, and you seem to indicate there is more
complicated logic involved than just the simple "Only show this question if
that question had and answer matching X". But this is a reasonable starting
point for something like this. As you develop your application further
you'll learn much more about the specific problem you're solving and come
up with much better ways of solving it.

Hopefully this large wall of text made some sense! Let me know if I can
explain something more. Hopefully this will be of some use to you.

Re: Importing contacts from email/social

[Asad Jibran Ahmed]

That would depend on the source of the contacts. Do you want contacts from
the users phone? I think those are in the vCard format, so you'll need a
library to read that. If you're looking for something like importing
contacts from Gmail, LinkedIn, etc, there are libraries for each of those
sources as well.

What's your source?

Just create a new file in whatever text editor you're using (I suggest

Re: Issue in filtering .....(want to show only the products that are sold and have status of paid in orders App)

[Asad Jibran Ahmed]

I'd need to see the full Cart model to confirm, but try something like this
to get all products for Orders with the paid status:

def get_products(self):
 orders = Order.objects.filter(user=self.user, status='paid')
 products_list = list()
 for o in orders:
  for p in o.cart.products:
   products_list.append(p)

 return products_list

This depends on their being a ManyToMany relationship to Product in the
Cart model.

Re: Issue in filtering .....(want to show only the products that are sold and have status of paid in orders App)

[Asad Jibran Ahmed]

Can you share the Cart model? The Order has a foreign key to Cart. I think 
that may be the model holding details of the products.

How are you associating a product with an order? Is there a way to get a
list of products sold for each order?

Re: Issue in filtering .....(want to show only the products that are sold and have status of paid in orders App)

[Asad Jibran Ahmed]

Hi,
 While you didn't show us the Product model, I assume it has a ForeignKey 
to the Order model. To filter for Products that have an Order with a sold 
status, you should look at the documentation for filtering on relationships 
at 
https://docs.djangoproject.com/en/1.10/topics/db/queries/#lookups-that-span-relationships.

Jibran

Re: multiple django installation in one server

[Asad Jibran Ahmed]

Hi,
 I have a similar setup for my projects. What I do is:

   1. Create a new virtual environment for the project (
   https://virtualenv.pypa.io/en/stable/). Virtual environments make sure
   that each project that you deploy can have it's own set of dependencies
   that do not conflict with the other projects.
   2. Install your required libraries in the virtual environment
   3. Use uwsgi in the Emperor mode to configure and run each app. Within
   the uwsgi config you can give it the virtual environment to use.

With this way I run multiple Django apps, each with different requirements,
on the same server without any issues. This involves a bit of
configuration, which may be daunting if this is the first time you're doing
this. If so, please do ask and I'm sure we can guide you further as well.

The number of projects that can be run on one server is very much dependent
on what kind of projects you are running, and the kind of traffic your
applications handle. My suggestion is to slowly add 1 or 2 projects at a
time and monitor the server to make sure it isn't overloaded. If not,
repeat. Otherwise get another server and setup the rest of the projects on
that.

Re: Django template iterating through two dictionaries/variables

[Asad Jibran Ahmed]

Unfortunately without knowing your project layout I can't show you exactly
how to load the filters, but you should give this a read:
https://docs.djangoproject.com/en/1.10/howto/custom-template-tags/.

Your template should look like the example from Ludovic.

Re: Django template iterating through two dictionaries/variables

[Asad Jibran Ahmed]

No problem. The most probable reason why you're getting the invalid filter 
error is because you forgot to load the filters.

Your explanation of the workflow is correct, with one small correction. The 
template will handoff the search for the correct *Score* to the filter 
function. Whatever the filter function returns will then be inserted in 
place of the {scores|from_player:person} part in your template. One way of 
getting the correct score would be to loop over the items in your scores 
dictionary, and find the one where the identification numbers match. One 
suggestion, instead of returning a dictionary from your filter function, 
you should return the value you want to display. So maybe your filter can 
look something like:
def get_score_for_person(scores, person):
 for s in scores:
  if s['Number'] == p.Number:
   return s['Score']


And you're right, maybe you can rename the filter to be get_score_for_person 
if that is more clear for your application.

Re: Django template iterating through two dictionaries/variables

[Asad Jibran Ahmed]

Since the example given by Ludovic uses the same variable names that are 
already present in your context, you won't need to change anything in the 
context dictionary. Just use 
{% load APP_NAME %}
on top of the template file to load the filter and you should be good to go.

Re: Django template iterating through two dictionaries/variables

[Asad Jibran Ahmed]

No need to change the context, since the variable names the example here
uses are the same as your existing context. It should work as long as you
remember to {% load APPNAME %} your filters in the template first.

Re: Hi, i'm new to django i need some mini project which contain atleast 4 page for go through how it works

[Asad Jibran Ahmed]

You could create a simple blogging application. Allow the user to create,
edit, and delete blog posts. And have a list page (home page) to show those
posts and a details page for the post.

Re: is it possible to manipulate image in PIL after uploading directly by its "request.FILES.GETLIST(FORMFIELD)" address not the saved picture on hard disk

[Asad Jibran Ahmed]

Hi,
 Every object in `request.FILES` is actually a file *liike* object that you
can use for processing. I guess you can use something like
`PIL.Image.frombytes` with the `request.FILES[filename].read()` data.

Django Doc for the `request.FILES`:
https://docs.djangoproject.com/en/1.10/ref/files/uploads/#django.core.files.uploadedfile.UploadedFile
Pillow (PIL Fork) documentation for the `frombytes` method:
https://pillow.readthedocs.io/en/3.3.x/reference/Image.html#PIL.Image.frombytes

Hope that helps.

Re: Running Django Project Locally

[Asad Jibran Ahmed]

One thing I'd add to this is that I could never work without runserver
because I tend to use ipdb a *lot* while debugging any problems. For me the
best way to debug is to put import ipdb; ipdb.set_trace() in my code and
just start debugging from the command line. Having uwsgi or any other kind
of server running my Django code takes away that ability, and I'd be in
hell trying to figure out errors without that.

Just my 2 cents.

Re: Running Django Project Locally

[Asad Jibran Ahmed]

Hi,
 It's definitely weird to not have a manage.py since all new Django 
projects should have it by default. But the manage.py file is pretty 
simple, and you can just paste this inside a new manage.py:

#!/usr/bin/env python
import os
import sys

if __name__ == "__main__":
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "main.settings")

from django.core.management import execute_from_command_line

execute_from_command_line(sys.argv)

Hope that helps.
Regards,
Jibran

Re: Models of Speedy Net

[Asad Jibran Ahmed]

Sorry, I just checked and I'm wrong about the ordering of elements in a 
class. The reason the constants need to be first is because you are using 
them when defining your fields. But other than that, the order doesn't 
matter.

Here's the code that I used to check this:

def get_const():
print 'get_const()'
return 1

def make_list(i):
return [i]


class A(object):
attr = make_list(CONST)
CONST = get_const()


print A.attr

When I tried to execute it I got NameError: name 'CONST' is not defined. If 
you change the class definition so that the CONST declaration comes first, 
it works.

Re: Models of Speedy Net

[Asad Jibran Ahmed]

The ordering of your attributes and methods inside the model class doesn't 
have to do with Django, it has to do with Python. Inside a class, the 
ordering doesn't matter as far as I understand. All of these documents you 
will find are thus just conventions to follow.

You could come up with your own if you want, but it's usually a good idea 
to stick to something already out there are used by a lot of people, as it 
makes it easy for new comers to your code to quickly navigate the code. 
Since this is an open source project using the Django style guide you have 
linked to sounds like a good option.

Re: django on apache server

[Asad Jibran Ahmed]

Not being able to load CSS points to an Apache config issue. Did you setup 
apache so your static root configured to serve files from your static 
folder? Your apache config might be helpful here.

Also, what you have pasted here seems like a warning, so while you should 
fix it, this is probably not the cause of your CSS loading error.

Re: Send mail after x hours

[Asad Jibran Ahmed]

Personally, I'd setup a simple cronjob on my machine that runs a Django 
management command. The command would get a list of users who are eligible 
to receive emails and send it to them.

I would have just used the send_mail directly from my management command, 
but if you already have a RQ setup for that, just go ahead and use the same.

This approach is simple and doesn't require using the rq-scheduler. But if 
you really want, using rq-scheduler is basically the same and the end 
result is similar.

Back button in a SessionWizardView

[Asad Jibran Ahmed]

We had a similar requirement in one of our products. We solved it by assigning 
the user a unique transaction id when they start the process, and saving all 
data in a temp db (redis) until the user completed the process. And whenever 
the user accessed a page with the transaction id in the get params, the data 
was autofilled in the form.

Maybe you can do something similar by saving data for each part of the wizard 
in a temp db under one key and using that to pre-populate the forms?

Also, we used keys that woyld expire after some time, thus if the user didn't 
complete the process, our db would start filling up with stale transaction data.

Hope that helps.
