Python/Django: Populating Model Form Fields with values from Imported JSON file
I have a model form that saves all form field inputs to the backend database as one entry. I also have a JSON file that contains multiple JSON objects whose fields corresponds to the model form field. This JSON file is being uploaded via FileField in the model. Ultimately, I want to be able to upload a JSON file with the multiple JSON objects into my model form and populate the fields with the corresponding values from the uploaded JSON file. Each JSON object will be a single entry to my database and they can have null values for at least one field. Ideally, I would like to be able to choose which JSON object (from the uploaded JSON file) gets loaded to my model form fields to eventually be saved in my database. How would I go about implementing this? -
The use of argparser instead of the OptParser in Django >= 1.8
I recently trying to learn about argparse in python, this gave me a hint on how programs like the Django framework and python itself give helpful Tracebacks for helping trace errors in a typical developers life :). I read about argparse in a few places to find out more and when I came across Django that changed from OptParser to argparser. What I know is argparser is just used for The program defines what arguments it requires, and argparse will figure out how to parse those out of sys.argv. The argparse module also automatically generates help and usage messages and issues errors when users give the program invalid arguments. My question is what does a command line parser like OptParser lack or what is better in argparse that made a huge framework Django change a cmd parser -
RadioSelect widget does not show labels in MultiWidget
I am trying to build a custom MultiValue field in django that consists of two widgets: RadioSelect and TextInput: if a user chooses 'Other' then they can insert the value there. Everything works, with one weird exception: the labels for radio buttons are not shown (see picture). Values are rendered ok, but the labels are just not there.

Need help creating catch-all url() entry using regex
So had zero issues with my Django and React URL routing in dev, but now that I am trying to move to production, running into all kinds of issues. Yes, I suck when it come to regex... definitely something I need to sit down and commit to learning. In dev, my catch-all was just the following which worked perfectly: url(r'', TemplateView.as_view(template_name='index.html')), In production, I got Uncaught SyntaxError: Unexpected token <. This, as it was explained to me, had to do with JS being caught in the url instead of index.html and that the JS needed to "pass through". I was told to try: url(r'^$', TemplateView.as_view(template_name='index.html')), This worked. The web application loaded and I was able to navigate. Another problem came up, however, when it came to verification emails and just with links in those am I running into issues with Page not found (404) which, again, wasn't an issue in my dev setup. The email links look like the following: https://test.example.com/auth/security_questions/f=ru&i=101083&k=6d7cd2e9903232a5ac28c956b5eded86c8cb047254a325de1a5777b9cca6e537 What I get back is this: Page not found (404) Requested URL: http://test.example.com/auth/security_questions/f%3Dru&i%3D101083&k%3D6d7cd2e9903232a5ac28c956b5eded86c8cb047254a325de1a5777b9cca6e537/ My react routes are the following: <App> <Switch> <Route exact path='/auth/security_questions/f=:f&i=:id&k=:key' component={SecurityQuestions} /> <Route exact path='/auth/*' component={Auth} /> <Route exact path='/' component={Auth} /> </Switch> </App> This … -
Django Authentication with Firebase/Firestore
I want to integrate Django authnetication with Firebase. I know for custom Django authentication I need to return a user object, the problem is my users are registered in Firebase's Firestore. I had the idea to work with request.session, where I can add ['uid'] on login and clear it on logout, but I am not sure if it is the best way. Is there any more official way for me to authenticate my users on Django with firebase's firestore? -

Django static files being generated with additional path
So, I'm using Django and pythonanywhere in order to setup an webpage, but I'm facing some issues when retrieving static files. I've followed the tutorial for static files (which is great btw) and everything works for the index.html page. However, when trying to go to a second page, it throws an error which fits one of the issues described in this other link: https://help.pythonanywhere.com/pages/DebuggingStaticFiles/ The path to the file and the path in the URL don't quite match (eg, there's an extra level of folder hierarchy in one and not the other) However, I don't know how to fix it... What is happening is that my log info shows that I'm loading: /static/pgbfiles/medicine.png -- this is working for the index.html /publicacoes/static/pgbfiles/img.css -- for the second page named publicacoes.html What I would like to have is all the static files in one single folder. They are already there but I don't know how to tell Django that they are all there for both html files... I think I could add an additional folder for the "publicacoes" files, but that is not what I would like to do atm. And this is how I'm loading the info on both index and publicacoes.html: … -
Dumped heroku database gives 'UnicodeDecodeError' exception on local machine
I'm trying to download heroku project (django) alongside with its database to another local machine. I've managed to download project with git and database through pg:backups.

How to set correct pagination href of next page if having arguments in url - django

ValueError: Missing staticfiles manifest entry for 'inline.bundle.js' django heroku angular
I am running django heroku and angular I am having an issue where I add new static files to django then upload to heroku, but the heroku instance keeps showing an old version of the code rather than the one I updated. I posted this question to address it. static file issue causing django 500 error? to which I was given an answer to do this: This is a common problem with whitenoise. I have wasted countless hours on this. Heres how you can deal with this issue. put these two lines in your settings.py DEBUG = False DEBUG_PROPAGATE_EXCEPTIONS = True and try to run the app on heroku. It will break just like it always did. Now go to https://dashboard.heroku.com/apps/<app_name>/logs Normally you wont be able to see logs when debug is False, but thanks to DEBUG_PROPAGATE_EXCEPTIONS=True you can see logs There, look for the file which whitenoise can't find and making whitenoise go haywire. In my case it was some random css file which was reference in my base.html. either you can fix its location or simply delete the line from base.html which references this file. after this, if tehre is issue with another file(s) keep doing it. Eventually … -
How do I make this regex utl pattern works in django 2
I need to make a url pattern which could work with this url: mysite.com/blog/12/بلاگ-مثال It contains utf-8 characters so I tried using \X: re_path(r'^blog/?P<blog_id>[\d+]+/(?P<slug>[\X.*]+)/$', views.single_blog, name='single_blog') But it didn't work. I don't know why. Maybe just because I'm not good in regex. So I tried a different pattern using just .* to accept anything: re_path(r'^blog/?P<blog_id>[\d+]+/(?P<slug>[.*]+)/$', views.single_blog, name='single_blog') But this also doesn't work and I get: The current path, blog/12/بلاگ-مثال, didn't match any of these. So as I mentioned I'm not good in regex, what's the right way to fix this? Is it the right time to say now I have two problems or regex is the only way? -
How do I create a session between an Android Application and Django Rest-Auth through Retrofit?
I am able to do the initial log in to the server and get the token, but when I try to do another request I get the HTTP error 403, so I am not actually being authenticated. When I go through the browser or the android application, this is the key that I am getting when I log in. { "key": "64ea43a78fa18da19364d2d0ae5a12371e5d0ee2" } Is there anything that I can do with this key using retrofit? I have tried using the header "Authorization" and following with the token. Here is my RestClient interface: public interface RestClient { @POST ("rest-auth/login/") Call<Token> login( @Body Login body ); @GET ("v2/users/{user}/") Call<List<CustomUser>> getUser( @Header("Authorization") String token, @Path("user") String user ); Here is the AsyncTask which will perform the requests to the server. The authenticateUser gives me an HTTP response of 200, but the syncUser gives 403. public class ActionSync extends AsyncTask<String, Void, Boolean> { RestClient client; IData activity; private static String token; public ActionSync(Context context) { activity = (IData) context; } @Override protected Boolean doInBackground(String... params) { Retrofit.Builder builder = new Retrofit.Builder() .baseUrl("http://" + params[2] + ":" + params[3] + "/") .addConverterFactory(GsonConverterFactory.create()); Retrofit retrofit = builder.build(); client = retrofit.create(RestClient.class); //Authenticate the user. authenticateUser(params[0], params[1]); //Once … -
Django form wizard: Operational error: cursor "..." does not exist

Select options in form will not show using Django

Calculate no of matches for __in or __contains lookup in Django
I'm trying to build a recommendation engine and one of the sub-task is to rank Venues on the basis of tags matched in from a list of tags available. I could do a __contains lookup in the filter to fitler the venues where some of the tags from the list already exists. But my motive is to also somehow know how many tags are matched for each venue so that I can allocate some rank to them. For example, give a rank of 10 for each matched tag. Here are my models: class Venue(TimeStampedUUIDModel): name = models.CharField(max_length=100, null=False, blank=False) tags = ArrayField( models.PositiveIntegerField( verbose_name=_('tag'), choices=TAGS_CHOICES ), null=True, blank=True ) Since tags is an ArrayField which can only contain choices defined by positive numbers, __contains lookup works in the filter query, but how can I annotate the no of matches? End result can be something like: venue_queryset.filter(tags_contains=tag_list).annotate(no_of_tags_matched=...) Please let me know if more information is needed. -
Django: Authorization using query parameters
I'm writing a chat app where registered users can send messages to each other. One of the components of this is a Django-based Messaging microservice, which has an API for sending and receiving messages. For simplicity, there are only two URLs: # List all messages in Thread "thread_id" GET /threads/<int:thread_id>/messages/?user_id=123 # Send a message as user "user_id" to Thread "thread_id" POST /threads/<int:thread_id>/messages/?user_id=123 This service is only visible internally, so there's no potential for spoofing user_ids. Authorization is based on user_id, which is passed to the service as a query param and processed like so: views.py: class MessagesViewClass(django.views.View): def get(request, thread_id): # If this user is not part of this thread user_id = request.GET.get('user_id') if this_user_not_part_of_this_thread(user_id, thread_id): raise Some403Exception() else: process_response_normally() Right now, I'm validating via a query parameter. Is there a more conventional or canonical way of handling authorization of this type? -
static file issue causing django 500 error?
I am using angular heroku and django. I have been noticing that when I use 'ng build' to build new static files to add to django then push to heroku, the heroku instance is showing a website that is several versions behind what my current code is. I attempted to run my django local server today after doing ngbuild placing my files in the designated folder, running python manage.py collectstatic which it runs successfully. then I run my django server, navigate to my page and I get a 500 response. Because I am using angular, I have set up my django server as a rest backend. every endpoint the rest service uses starts with the url api/ so localdomain/api/ <-- restful service localdomain alone serves the angular app. I only receive the 500 sever error when I try and get the app served.

I already made the textcompare program in python and the first two webpages that will take the uploaded files and store it in one folder with the textcompare.py The last webpage that i'm having problem with has only one button that says execute.

Django select multiple objects
I have a set of community objects defined by the following model: class Community(models.Model): name = models.CharField(max_length=20, unique=True) banner = models.ImageField(upload_to="communityBanners", blank=True) creation_date = models.DateTimeField(default=timezone.now) I've made it so that users are able to create new communities. However, I want to also make it so that other users can go to a multiple choice form and select which communities they want to join, then hit submit and store the preferences. Since the communities are objects, how do I create a multiple choice object field and form that they can select those? I'm under the impression that ModelChoiceField will not work here since I want to be able to select one, all, or any number in between of objects.
