DRY-rest-permissions somehow does not check my object permissions except global permissions
I have recently started implementing dry-rest-permissions, but I can't seem to get it to check the has_object_permissions, it appears that only the global permissions work for me. I am fairly new to implementing permissions and this is my first time implementing DRY-rest-permissions and have only recently started coding in django rest framework, so apologies for the lack of knowledge in advance. At the moment I am trying to delete a company object by simply having a user call a URL, that URL then gets the current user's active_company and then deletes it only if the current user is the active_company's company_owner. But what I discovered, is that I somehow can't get has_object_permissions to work anywhere? I have noticed that if I delete has_write_permission(request), and hit the company_delete URL it gives me the following error: '<class 'company.models.Company'>' does not have 'has_write_permission' or 'has_company_delete_permission' defined. This means that it doesn't even look for the has_object_company_delete_permission. Meaning it only checks the global permissions rather than any of the object permissions, what am I possibly doing wrong here? My model: class Company(models.Model): company_name = models.CharField(max_length=100) company_orders = models.IntegerField(blank=True, null=True) company_icon = models.ImageField( upload_to='media/company_icon', blank=True) company_owner = models.ForeignKey( User, on_delete=models.SET_NULL, blank=True, null=True) company_employees = models.ManyToManyField( … -

Django + JavaScript(jQuery) dynamic removal of dropdown option?
I am working on a backend Django project which uses a Bootstrap selectpicker. I am working on an edit view, and having trouble removing certain dropdown select options, based on the users previous saved information. I have tried using jQuerys .remove() .hide() and plenty other options but all select options still show. The dropdown provides a list using a django context proocessor <div class="form-group"> <label>Job Type</label> <div class="select-panel"> <select class="selectpicker" name="job_type" id="edit_job_type"> <option value="">Select</option> {% for obj in job_type %} <option value="{{ obj.name }}" second_job_cat="{{ obj.second_job_cat }}">{{ obj.name }}</option> {% endfor %} </select> </div> </div> And then in the JS popup modal GET request, that provides the popup modal form with the users existing data. // grab from the django view the users previous job type. let select_job_type = data['edit_job_type']; // set the value to previous value $("#edit_job_type").selectpicker('val', select_job_type); $("#edit_job_type").selectpicker('refresh'); This is the function I am trying to use to remove the values I do not want. let second_job_cat = document.getElementById('edit_job_type'[sel].dataset.secondJobCat; $("#edit_job_type > option").each(function() { if (second_job_cat !== this.dataset.secondJobCat){ console.log($(this).val()) $(this).remove() // also tried $(this).val().remove() } }); When I console.log the $(this).val() it does log all of the option values I do not want, which should be a good sign? … -
Database querying
I'm having an issue here that I want clarification with, see, I'm making a program that does analysis of data. I wanted to query data from different users, the data is numerical by the way, whenever I'd get subject marks from a user, I want the system to return the name of the user who has those marks. It was all working fine until I tried querying the users with the same marks, and all I could get was an error analyzer.models.ResultsALevel.MultipleObjectsReturned: get() returned more than one ResultsALevel -- it returned 4! So I was trying to find a way to still query and return the name of users with that subject mark, even if they have the same marks. I believe that should be possible since the users have different id's and stuff, help would be much appreciated! Here's my views.py biology_marks = [] for student in ResultsALevel.objects.all(): biology_marks.append(student.advanced_biology_1) value_1_biology = ResultsALevel.objects.get(advanced_biology_1=biology_marks[-1]).student_name.last_name value_2_biology = ResultsALevel.objects.get(advanced_biology_1=biology_marks[-2]).student_name.last_name value_3_biology = ResultsALevel.objects.get(advanced_biology_1=biology_marks[-3]).student_name.last_name value_4_biology = ResultsALevel.objects.get(advanced_biology_1=biology_marks[-4]).student_name.last_name -
Avoid invocation of a business logic by looking up a table column value without race-condtion
Is the possible to to effectively block invocation of a function by looking a database table column value. I've a model(LookupTable) as follows, In my app(Django + Postgres) There is a chance that 'my_function' is called in two ways 1. by a third party(via API call) after a particular event happened and 2. by my own job ( call after some fixed time after particular event happened) I want to make sure 'my_function' is called either by third party or by my own job for a 'unique_id'. My plan is to look the 'LookupTable' status column and to determine whether to continue the execution of 'my_function'. Once any of the process invoked the function mark the status from 'I' to 'U'. I use the following strategy to make sure, if both the process start work at the same time LookupTable(models.Model): some_unique_id = models.CharField(max_length=256) status = models.CharField(choices=(('I', 'Initiated'), ('U', 'Updated'))) @transaction.atomic def my_function(unique_id): # The following call is invoked only if status is 'Initiated'. lookup = LookupTable.objects.select_for_update.filter(some_unique_id=unique_id, status='I'). # only one record per unique_id if not lookup: return lookup.update(state='U') # My business logic which create/update some records in some other table ---------- ---------- I've used 'select_for_update' and transaction to block other … -
Django and Bootstrap: prevent warning box from appearing if there is an empty string
I'm using Django templates and Bootstrap to render a red alert box if there is a message. The code is: views.py else: return render(request, 'auctions/listing.html', { 'listing': listing, 'form': BidForm(), 'message': '', 'comments': listing.comments.all() }) listing.html <div> <p>Starting Bid: {{ listing.starting_bid}}</p> <p>Current Bid: {{ listing.price }}</p> <div class="alert alert-danger" role="alert" style="display: inline-block;"> {{ message }} </div> </div> The red warning box renders if there is no message (i.e. an empty string), which seems sensible and intuitive. However, when I remove message from views.py altogether, the red warning box still renders. else: return render(request, 'auctions/listing.html', { 'listing': listing, 'form': BidForm(), # 'message': '', 'comments': listing.comments.all() }) What am I doing wrong here?
