Django not rendering background images used in url <style> tag
I am trying to render static image files with Django and this is the first time I have encountered images referenced with the <div class="img" style="background-image: url;"></div> style tag. I will upload the code and the site as is showing when I run the server. <div class="founder d-flex align-items-center mt-5"> <div class="img" style="background-image: url('/static/images/doc-1.jpg');"></div> <div class="text pl-3"> <h3 class="mb-0">Dr. Zen Goode</h3> <span class="position">CEO, Founder</span> </div> </div> This is what the output shows when I run the server. (Of course, it shows other image files here but I assume its just the same): [22/Jul/2022 06:04:36] "GET /static/images/person_2.jpg HTTP/1.1" 404 1816 django.core.exceptions.SuspiciousFileOperation: The joined path (S:\maps.googleapis.com\maps\api\js?key=AIzaSyBVWaKrjvy3MaE7SQ74_uJiULgl1JY0H2s&sensor=false) is located outside of the base path component (C:\Wor\dentistt\dentist\static) [22/Jul/2022 06:04:36] "GET /static/images/doc-4.jpg HTTP/1.1" 404 1807 [22/Jul/2022 06:04:36] "GET /static/images/person_1.jpg HTTP/1.1" 404 1816 [22/Jul/2022 06:04:36] "GET /static/images/person_3.jpg HTTP/1.1" 404 1816 [22/Jul/2022 06:04:36] "GET /static/website/https%3A/maps.googleapis.com/maps/api/js%3Fkey%3DAIzaSyBVWaKrjvy3MaE7SQ74_uJiULgl1JY0H2s%26sensor%3Dfalse HTTP/1.1" 500 59 [22/Jul/2022 06:04:36] "GET /static/images/person_4.jpg HTTP/1.1" 404 1816 [22/Jul/2022 06:04:36] "GET /static/images/image_3.jpg HTTP/1.1" 404 1813 [22/Jul/2022 06:04:36] "GET /static/images/image_1.jpg HTTP/1.1" 404 1813 [22/Jul/2022 06:04:36] "GET /static/images/image_2.jpg HTTP/1.1" 404 1813 And this is the site: I know that with the 404 error, the files are not being found so how I can render the image correctly here? -
CORS, HttpOnly, CSRFCookie; Django; ReactJS
I have a question. I am developing a webApp. My backend is on xxxx.xxxx.xxxx.xxxx:8000 and my frontend is on xxxx.xxxx.xxxx.xxxx:3000. I am using Django and ReactJS. I have configured my CORS policies on the backend to allow only my fronted to make requests. So. Whenever I have to get CSRF cookies from my backend they come in a response under Set-Cookie with HttpOnly flag. My question is if we are not supposed to extract HttpOnly cookies with the JS how come I still can do that with my ReactJS app. However, whenever I remove that flag I cannot set or retrieve those cookies from the header anymore. Whta is wrong? Or what is right? Help me to understand that please. my django CORS setup: # CSRF Cookie Settings CSRF_COOKIE_AGE: Optional[int] = None CSRF_TRUSTED_ORIGINS = [ 'http://localhost:3000', 'http://xxxx.xxxx.xxxx.xxxx:3000' ] CSRF_COOKIE_HTTPONLY = True # CORS(cross origin resource sharing) settings CORS_ORIGIN_ALLOW_ALL = False CORS_ALLOW_CREDENTIALS = True CORS_ALLOWED_ORIGINS = [ 'http://localhost:3000', 'http://xxxx.xxxx.xxxx.xxxx:3000', ] CORS_ALLOW_METHODS = [ 'DELETE', 'GET', 'PATCH', 'POST', 'PUT', ] my reactjs request: fetch("http://xxxx.xxxx.xxxx.xxxx:8000/get_csrf",{ method: 'GET', mode: 'cors', credentials:'same-origin', headers: { 'Accept': 'application/json', 'Content-Type': 'application/json' } }) .then(response => { console.log(...response.headers) response.json() }) .then( (result) => { console.log(this.getCookie('csrftoken')) }, (error) => { … -

How to Annotate Expense Sum From Another Table Through Fields That Aren't Date or DateTime Field
I am trying to annotate the sum of Interest Expense on Loans that got some Interest Expense during a day. My Data looks like this. Loan id, number type ..., InterestExpense (This is Many to One Model) id, loan_id (FK to Loan) amount day (positive small integer with Validator). (Unfortunately, doesn't respect DD format) month (positive small integer with Validator) (Unfortunately, doesn't respect MM format) year (positive small integer with Validator)(Respects YY format) So given start and end date I need to get sum of amount of InterestExpense for loans grouped by Loan Type. Dilemma I am having is I can't seem to create or annotate a date field out of those day, month, year small integer values. I tried Concat with to_date. But it doesn't like it has 1 digit months. initial_report_data = self.primary_report_model.objects.filter( ... (SOME FILTER) ).select_related('interestexpense').annotate( interest_date=Func( Concat('interestexpense__month', Value('-'), 'interestexpense__year', Value('-'), 'interestexpense__day', output_field=CharField()), Value('MM-YYYY-DD'), function='to_date', output_field=DateField() ) ) I am getting errors of Date Being Out Of Range Because For Month And Day Values, the digits from 1-9 aren't 0 padded. Is there a way I can get any date/datetime/timestamp value from those (Month, Day, Year) Fields So I can see if it is in range of … -

How to test Django reusable templates?
In one of my templates for detailed view of a device assignment I had logic pertaining to if buttons should appear depending on the user's permission. I wrote tests for these buttons and they work as expected. Today I wanted to reuse these buttons elsewhere in another template so I extracted it into its own template file and put it in a "partials" folder. |-templates | |-assignments | | |-deviceassignment_form.html | | |-deviceassignment_detail.html | | |-deviceassignment_confirm_delete.html | | |-deviceassignment_list.html | | |-partials | | | |-deviceassignment_control_buttons.html | | | |-deviceassignment_infobox.html Obviously I can continue testing deviceassignment_detail.html which includes the control buttons and checks to make sure they work (appearing or not based on permissions). But then when I include control buttons elsewhere I might be tempted to test them again... Instead couldn't I write a test ONLY for the deviceassignment_control_buttons.html template? I want to render the template directly with a basic view context and check that everything works as expected. Is this possible? -

How to prevent Django view to mix up data of two different users

Django_rq, jobs fails due to missing positional arguments
I've been trying to solve an issue with integrating Django_rq into my app. I have several .csv data imports that I have created which take quite a bit of time to process. All data imports are similar in nature, but vary in the amount of code being preformed. I have updated two of the data imports so far to use Django_rq and they run successfully. No issues with them. Little backstory, all these functions where using python threading module originally. The problem came when I went to update the 3rd data import function. In addition to updating it just like the first two, I reduced the amount of positional arguments from 5 down to just 1. When I run the data import and add the job to a queue, it fails immediately. When I check the failed job registry to review the trace back, it says Traceback (most recent call last): File "/srv/cannondj/venv/lib/python3.8/site-packages/rq/worker.py", line 1061, in perform_job rv = job.perform() File "/srv/cannondj/venv/lib/python3.8/site-packages/rq/job.py", line 821, in perform self._result = self._execute() File "/srv/cannondj/venv/lib/python3.8/site-packages/rq/job.py", line 844, in _execute result = self.func(*self.args, **self.kwargs) TypeError: process_task_data() missing 5 required positional arguments: 'all_jobs', 'all_tasks', 'all_assignment_types', 'all_assignment_statuses', and 'db_que' I find this odd, because those are the … -
How to constrain foreign key to field in other foreign key?
Sorry for the horrible question title, I'm not sure how to phrase this. Here's a dummy example to make things clear. If I have models like: class Shop(models.Model): mechanics = models.ManyToManyField(mechanic) class Mechanic(models.Model): name = models.CharField() class Car(models.Model): problem = models.CharField() shop = models.ForeignKey(Shop, on_delete=models.SET_NULL, blank=True, null=True) fixer = models.ForeignKey(Mechanic, on_delete=models.SET_NULL, blank=True, null=True) How do I restrict the model so that fixer is always only ever a mechanic in the same shop as the car? Hopefully this is straight forward, but I've been scouring the Django docs and Stackoverflow and things haven't quite come together. I've looked into using a CheckConstraint on the model, but I'm not sure how to format the query. I've also learned about the limit_choices_to of a ForeignKey, but have run into a similar problem. Any help is appreciated. Thank you! -

File uploaded in my form is not showing up in my edit/update form
When I fill out my form with its file, it apparently submits, but when checking it out when editing/uploading, all data in the form shows up except my file. So, I cannot access it at all. I guess it probably has something to do with my views.py (the function is for both, save a form for the first time and visualizing them), so here it goes #views.py def contract_form(request, id=0): if request.method == "GET": if id == 0: form = ContractsForm(request.FILES) else: contratos = Contratos.objects.get(pk=id) form = ContractsForm( instance=contratos) return render(request,"contracts_form.html", {'form':form}) else: if id == 0: form = ContractsForm(request.POST, request.FILES) else: contratos = Contratos.objects.get(pk=id) form = ContractsForm(request.POST, request.FILES, instance= contratos, ) if form.is_valid(): form.save() messages.success(request, "Form submission successful") else: messages.error(request, "Error, contract not submitted") return redirect('/contracts') Just in case, every other instance that has something to do with the upload file: #models.py attached_file=models.FileField(upload_to="media", blank=True) My form is stated with <form enctype="multipart/form-data" action="" method="post" autocomplete="off" class="row g-3"> #contracts_form.html <label for="{{ form.subject.id_for_label }}">Attached File:</label> {{form.attached_file}} {% if Contracts.media %} <a href="{{Contracts.media.url}}"></a> {% endif %} #settings.py MEDIA_ROOT=os.path.join(BASE_DIR, 'uploads/') MEDIA_URL="/contracts-media/" path('contracts/edit/<int:id>', views.contract_form, name='edit'), #edit/update form path('contracts/add', views.contract_form, name = 'new-contract'), #add a contract ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) ```` -

usage of django context variable as html tag attribute

Fixing a typo in models.py and migration for django python project
I'm working on my first django project following along with a youtube tutorial. In models.py while following along I made a typo... crated_at = models.DateTimeField(default=datetime.now) "crated_at" should be "created_at". The typo is reflected in my migrations. I tried changing both models.py and the migrations py file but it leads to an error so I changed it back to "crated". I think the problem is that the database saves the information as "crated_at". I don't want to delete the migration and redo the migrations because from what I read the database is already labeled and it won't fix the problem. Also, I don't mind if it's left as "crated_at" in models.py and the migrations, but at least I would like it to see "created at" when I'm signed in as admin. I want to move on but when I sign in as admin "crated at" is staring me in the face. I feel like this is a good learning moment. Thank you. -

Django - Storing user-defined querying logic in a model
I'm making a school app with DRF. Teachers are able to create Exercises and associate them with Tags. An Exercise is thus in m2m relationship with Tag: class Exercise(models.Model): MULTIPLE_CHOICE_SINGLE_POSSIBLE = 0 MULTIPLE_CHOICE_MULTIPLE_POSSIBLE = 1 OPEN_ANSWER = 2 JS = 3 C = 4 EXERCISE_TYPES = ( # ... ) DRAFT = 0 PRIVATE = 1 PUBLIC = 2 EXERCISE_STATES = ( # ... ) exercise_type = models.PositiveSmallIntegerField(choices=EXERCISE_TYPES) state = models.PositiveSmallIntegerField(choices=EXERCISE_STATES, default=DRAFT) text = models.TextField(blank=True) tags = models.ManyToManyField(Tag, blank=True) class Tag(models.Model): name = models.TextField() Teachers can use tags to create quizzes that randomly select exercises with certain tags. In order to do this, there's a Rule model, to which one or more Clauses are related. A Clause is in a m2m relationship with Tag. Let's say a Rule has two Clauses associated; the first clause is associated to tag t1 and t2, and the second clause is associated to t3 and t4. The Rule logic will pick an exercise that has these tags: (t1 OR t2) AND (t3 or t4) class EventTemplateRule(models.Model): pass class EventTemplateRuleClause(models.Model): rule = models.ForeignKey( EventTemplateRule, related_name="clauses", on_delete=models.CASCADE, ) tags = models.ManyToManyField(Tag, blank=True) The actual query is constructed at runtime using repated filter applications and Q objects. … -
