Is there a maximum length for django request URL?
I was trying to send a get request to django beackend which encodes a list of ids that I need. I noticed that when this list of id(string) goes too long, the django will not handle this request. I can see the request in the django test server, but it never actually enter any view. In the browser, nginx gives me 404. URL: "/xxx/xxx/xxx?type=xxx&ids=4918230_25808605%2C4996758_49144848%2C5121093_43940616%2C56944804_40780188...." I know I can maybe use post to encode params in the body instead, but I just want to find out the reason behind this. -
Is Celery needed for asynchronous file writing functionality in Django?
I'm planning to add some functionality to my Django app that will write a row of data to a csv file when certain views are called: session_dict = collectUserDataFromRequest(request) #....collect parameters from request if os.path.isfile(filename): with open(filename, 'a') as csv_file: a = csv.DictWriter(csv_file,session_dict.keys()) a.writerow(session_dict) csv_file.close() else: with open(filename, 'w') as csv_file: w = csv.DictWriter(csv_file,session_dict.keys()) w.writeheader() w.writerow(session_dict) csv_file.close() # then proceed to render the html A problem I am facing is dealing with potential race conditions when multiple users are accessing my app at the same time. While the data can be added to the csv file in any order, I don't want some user's to wait longer for a view to load while waiting for a lock to be released on the csv file. As such, I think an Asynchronous queue of string data to be written to the file that can run in the background sounds like a good workaround. I have been told that Celery is a good framework for adding asynchronous processes to my Django app. But looking through several tutorials, I am seeing that additional frameworks such as Redis are usually required. I worry that this may be overkill for what I aim to accomplish. Will … -
Solr nested documents vs. grouping/field collapse (via Django Haystack)
I'm working on a website that's running Django with Solr as it search backend. Haystack functions as Django's interface to Solr. I currently have one Solr collection, Apps. Apps each have multiple releases, but in Solr they manifest as one (most recent) release per app. I've come up against a limitation for that architecture: I need to be able to search all of an app's releases and return the most relevant one. Example data in Django ORM: App Foo - Release A - released Nov 2017, compatible with Linux - Release B - released April 2017, compatible with Windows Example search in Solr: Give me all the apps with a release that's compatible with Windows Expected: App Foo is returned. Actual: App Foo is not returned because we're only storing Release A's metadata in the App Foo document in Solr. A solution I'm pursuing is to index Solr based on Release rather than App. But when we do that, how do we use Solr/Haystack to return only the most recent release that matches the query? It seems like Result Grouping / Field Collapsing might solve the problem: http://yonik.com/solr-result-grouping-field-collapsing/ But does Haystack support it? If not, is there a way to … -
Is there a better way to make this queryset using Q? django
I have a query which uses filter but I know there is this thing called Q but trying to play around with it, I am not sure how I can use Q. I am not sure which one would be better but trying to know another way to do the query. What I actually want to do is... for my queryset return I have a default field and two input fields which are options. let's say, language in default is english, there is a location and title field. If location and title fields are available, make a query to query location, title, and language. If only location then only query location and language, if only title then only query title and language. I have done it two ways, one with filter only which has less code... postings = Posting.objects.filter(language='EN') if kwargs.get('title'): postings = postings.filter(title__icontains=kwargs.get('title')) if kwargs.get('location'): postings = postings.filter(location__icontains=kwargs.get('location')) the above does work with using only filter I am trying to see if I can do it with using Q but cannot seem to make it work I have something like this at the moment if title and location: postings = Posting.objects.filter(title__icontains=title, location__icontains=location, language='EN') else: queryQ = Q(posting_language='EN') if title: … -
Django - Trying to a field that is not in the form but is in the model
Right now I have a model.form with one field nothing more, but the model has 3 fields(see reference down below) and 1 of them set by the form, one has a default to false as it should be and the last one I will set in the view but it won't correctly do it and idk why.

Test results of POST in django custom admin actions django 1.11
I am still very, very new to python and django, so please forgive my ignorance: I am trying to write a test for my custom admin action and the custom action appears to be working, but the test is still failing. I am missing something. I tried to apply the answers from this post: Testing custom admin actions in django The objects are being created correctly, and they have primary keys, but the changes are still not being reflected after I post to the action.

CSRF token missing or incorrect when trying to upload a file with ajax
I have a file upload form in html with which I'm trying to upload a file(and file size to display) via ajax call. I'm using django. Here's the upload form: <form class="uploadForm" method="post" enctype="multipart/form-data"> {% csrf_token %} <input type="file" id="uploadFile"> <input type="submit" class="button" id="uploadButton" value="Upload"> </form> Here's my Jquery + Ajax: $('.uploadForm').on('submit', function(event){ event.preventDefault(); var fileSize = ($('#uploadFile')[0].files[0].size/1024); var fileName = $('#uploadFile')[0].files[0].name; var realSize = sizeConverter(fileSize); var fileData = new FormData($('#uploadFile').get(0)); $.ajax({ url: '{% url 'project:uploadFile' %}', type: 'post', data: { 'uploadedFile': fileData, 'fileSize': realSize, csrfmiddlewaretoken: '{{ csrf_token }}' }, cache: false, processData: false, contentType: false, success: function(data){ alert(data); } }); }); And in views.py I have this: class uploadFile(TemplateView): template_name = "project/uploadFile.html" def post(self, request): fileSize = request.POST.get('fileSize') return JsonResponse(fileSize, safe=False) With the above code I get Forbidden (CSRF token missing or incorrect.) error. I googled this and someone here suggested removing processData and ProcessType. When I remove those two parameters absolutely nothing happens when I submit the form(nothing in the console neither). What could be wrong with this? Thanks. -

Save calculated value as a model field
As a follow up to my eariler question I have a new one. How can I save this calculated value as a model field. I would like to use it in my views and templates to order list by this field.

Override django change_form.html template when a third app is overriding it
I am trying to override change_form.html only for one model, so I did as explained in the django documentation and created /templates/my_app_name/my_model_name/change_form.html. The problem is, it is not working and I am not seeing the extra features that I have added to the change_form template. I am using django_guardian, which also overrides the same template, so my assumption is that this is causing the issue. It is worth mentioning, that before placing the template in the my_app_name/my_model_name/ folder, the features of both templates were visible in the admin interface. Is there a way to apply this only for 1 model? -
How validate initial values in a Django formset
I am developing an application which where the user to uploads a text based data file (CSV), validates the data file, and displays the data in a form with any error messages so that the user can correct the errors and then commit the data to the DB. I'd like to have the Formset (which displays the records) validate the initial data but I can't seem to get the formset to indicate that it is bound and thus validate (everything displays OK just can't get it to validate). Any advice on how I can pull this off? I've poked around this site and seen a lot of discussion that comes close to answering my question but haven't quite found the solution yet. Thanks in advance! Here's my form code: class BasePITReleaseFormset(BaseFormSet): def clean(): #haven't gotten to coding this part yet return super().clean() class PITReleaseFormsetHelper(FormHelper): def __init__(self, *args, **kwargs): super(PITReleaseFormsetHelper, self).__init__(*args, **kwargs) self.form_method= 'post' self.layout = Layout( 'field1', 'field2', ...

Django Formview Won't Validate
Django newbie here. I recently implemented a simple search with Django. I user specifies data in search bar, search is executed. I was able to determine today how to get the search to be null if user clicks on empty search bar. What I'm really trying to accomplish is to implement error logic so that the user has to specify data in the search bar. This has been very straight forward with all of the other views, but the search is a bit trickier, for me anyway. I have done several SO searches today, and determined that my HTML get method is ok for a search, but it may be causing some problems with the FORMVIEW that I am using. I have also tried to override POST and GET for the FORMVIEW, but can't seem to get it to work. I want to stick with CLASS BASED VIEWS, so I am using FORMVIEW. Here is my code.... My HTML <form method="GET" autocomplete=off action="{% url 'Book:book_request_search_results' %}" > <div> <h1 class="title">Book Request Search</h1> </div> {{ form.non_field.errors }} <div class="section"> <input type="search" class="name2" name="q"> </div> <div class="section"> <input type="submit" id="" class="submit6" value="Search"> </div> My VIEWS.PY class BookRequestSearchView(LoginRequiredMixin,FormView): form_class = BookRequestSearch template_name = … -
Correct structure for a Django application and handling the views and sub views
I struggle a bit in order to understand how a Django Application should be properly structured. In particular, I struggle to get my head around the views. So I have this file base.html And I know that this file will have common elements of the whole application such as footer, navbar, head etc. So far so good. Inside my base.html file I will have the tag: {% block content %} {% endblock %} Which handles the dynamic content of the application. Now I create a static page called home.html and inside that file I put {% extends 'base.html' %} ... Whatever I want {% block content %} And now comes the part that I really struggle to understand how it works. I create a new app called dashboard. I create a dashboard.html file and similarly to home.html I extend the base, and but elements inside the content block. In the views.py of the generated application I define: @login_required(login_url="login/") def dashboard(request): return render(request, "dashboard.html") and the dashboard.html {% extends 'base.html' %} {% block content %} <div class="dashboard-page"> <div class="row equal-sides"> <div class="col-sm-2 trim-right"> {% include 'dashboard_navigation.html' %} </div> <div class="col-sm-10 trim-left"> <div class="dashboard-main card"> <h3>Welcome to your dashboard</h3> </div> </div> </div> … -

Django issuing extra GET request
I recently noticed that every page I navigate to in my app automatically issues a second GET request. Doesn't matter if the initial request is GET or POST. I've spent all day digging around the web, and came across this question. It's the same issue, but I've done all of the solutions suggested in the responses (make a blank template, APPEND_SLASH=False, take out all tags to load resources, no link rel="shortcut icon" in my templates), and I still get the double request. Here is the output from my log with the requests for a page that is just a blank template: "GET /app/norepeat/ HTTP/1.1" 200 89 Not Found: /favicon.ico "GET /favicon.ico HTTP/1.1" 404 4719 "GET /app/norepeat/ HTTP/1.1" 200 89 And here is the view for that URL: def norepeat(request): return render(request, 'norepeat.html') And norepeat.html is a blank html file. Any ideas what is going on here? I know that this doesn't really affect my app's functionality, but I would rather that my server doesn't get hit with double the requests when my app is in production. Thanks! -
