Django SiteTree: menu renders but breadcrumbs doesn't when variable is in url
I am using django==1.11 and django-sitetree==1.9.0, all links without url variables render both on menu and breadcrumbs but urls with variables only render on menu(with correct links) and not on breadcrumbs.

User Edit Profile Form won't edit all fields,Django
I have created a registration form using django's usercreation form. And have then created a EditProfileForm using the registration form. My Issue is that EditProfileForm uses User Model,and Birthdate field is in Profile Model,so I am able to edit all fields except Birthdate as it is not from the user model. How do I go about editing birthdate,or creating a form where I can edit all fields instead of only the user fields? My Model for Profile class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.PROTECT) def __str__(self): return self.user.username; USWEST = 'usw' USEAST = 'use' EUROPE = 'eu' OCEANIA = 'oce' ASIA = 'as' SOUTHAMERICA = 'sam' SOUTHAFRICA = 'saf' MIDDLEEAST = 'me' PREF_SERVER_CHOICES = ( (USWEST, 'US-West'), (USEAST, 'US-East'), (EUROPE, 'Europe'), (OCEANIA, 'Oceania'), (ASIA, 'Asia'), (SOUTHAMERICA, 'South America'), (SOUTHAFRICA, 'South Africa'), (MIDDLEEAST, 'Middle-East'), ) pref_server = models.CharField( max_length=3, choices=PREF_SERVER_CHOICES, default=USWEST, ) birth_date = models.DateField(null=True, blank=False,) sessions_played = models.IntegerField(null=False, blank=False, default='0',) teamwork_commends = models.IntegerField(null=False, blank=False, default='0',) communication_commends = models.IntegerField(null=False, blank=False, default='0',) skill_commends = models.IntegerField(null=False, blank=False, default='0',) positivity_commends = models.IntegerField(null=False, blank=False, default='0',) FORMS.PY from django import forms from django.contrib.auth.models import User from django.contrib.auth.forms import UserCreationForm, AuthenticationForm from apps.api.models import Profile, Feedback from django.forms import ModelForm #form to create profile #RegistrationForm VIEW must be … -

Django manytomany m2m_changed script works, but how?
I have a model: class Course(models.Model): class Meta: ordering = ['completion_order'] degree = models.ForeignKey(Degree, on_delete=models.CASCADE) name = models.CharField(max_length=30, null=False, blank=False) completion_order = models.PositiveSmallIntegerField(default=0,null=False, blank=False) required = models.ManyToManyField('Task', default=1, blank=True, symmetrical=False) And I have written a function to run on "m2m_changed" to automatically adjust the completion order to take into account any changes in prerequisites: def required_changed(sender, instance, **kwargs): degreecourses = Courses.objects.all().filter(degree=instance.degree) for zcr in degreecourses: #resets the order for the all the degree's course instances zcr.completion_order = 0 for cr in degreecourses: #assigns new completion_order values if cr.required.count() is 0: # if no requirements sets 'completion_order' to 1 cr.completion_order = 1 else: #sets 'completion_order' to the increment of the highest (max) value of this courses's required course mx = cr.required.all().aggregate(Max('completion_order')) neworder = mx['completion_order__max'] + 1 cr.completion_order = neworder cr.save() This is run after any change in the m2m thus: m2m_changed.connect(required_changed, sender=Course.required.through) I originally set this up iterating through multiple times, but then realised it was unnecessary -my (novice) question is: Can someone explain how this is able to resolve all of the "required" values in one pass, i.e. without having to iterate through the second loop multiple times? I'm guessing it's to do with python being object oriented - but … -
django queryset method on related model filter

Validate csv file submitted with Django form without loading into memory
I'm building a django app that will let people upload CSVs that will be stored in S3 (based on django-storages) then processed by celery tasks which will then ingest them into the database. These CSVs can be any size, from a few rows (where Django would store it as a InMemoryUploadedFile) to hundreds of megabytes (where django would use aTemporaryUploadedFile.) I'm using a simple ModelForm on a generic CreateView, but I want to add a way to check the first row in the file (the header) to validate that the CSV has all the columns I need. This would be pretty simple if I knew the path of the file. I'd just use python's standard file and csv handling functionality to read the first line into the csv module and check the fields. But how do I do that using an uploaded file where it may be in memory or it may be a temporary file, inside the modelform? Without loading the file into memory? -
Jsonify an array of django object

Cache in only in Django (as database caching) and not in browser
I've tried a lot of things, and they all failed. My Django (2.0) website has some pages which take a lot of time to generate. I want to keep this pages in the database cache of the Django server until the database changed. My goal: Have pages ready in database cache Serve users the cached pages Don't save these pages as cache in the browser (the browser can't know if the page needs to be re-generated) Keep .js files etc as cache in browser Don't use browser cache when using the browser 'back' button to go back to the calculation heavy page The closest I got was to enable database caching, enabled per-site caching, and using cache.clear() on receiving post_save and post_delete signals. But still, if I pressed 'back' in my browser, the local cache was used (so no request was send to the server). I tried to fix this by adding @never_cache to the view, but this also prevented caching in the middleware... -

injecting code inside of code python django and q objects
This question gets me close to what I want to do but I am still in need of further understanding. Django. Q objects dynamicaly generate I have a view in django that looks to see if any query params have been sent to the url. I am expecting some query objects to have multipule values. ie. domain.com/?neighborhood=Logan Square&neighborhood=River North I grab queryparams and put them in a list. I am now trying to iterate through that list and filter through the query params using or logic. https://docs.djangoproject.com/en/1.11/topics/db/queries/#complex-lookups-with-q for this I know I need to use Q objects. the proper code for this is: Q(neighborhood='Logan Square') | Q(neighborhood='River North') so what I need to do is 1 adding a query Q object dynamically and then also adding the | operator dynamically for all objects in the for loop. -
Django queryset: Exclude all row(s) if any one row with same id is excluded
I am using Django query to filter out some transactions from table where one transaction might have multiple entries in the table. E.g. Sample table +---------------+---------+ | TransactionId | Status | +---------------+---------+ | Txn0 | Pending | | Txn0 | Success | | Txn1 | Fail | | Txn2 | Pending | | Txn3 | Fail | | Txn4 | Pending | | Txn4 | Fail | | Txn5 | Pending | +---------------+---------+ Current query : SampleTable.objects.exclude(status='Fail').exclude(status='Success') My current query returns Txn0, Txn2,Txn4, Txn5( because these are marked pending). I need a queryset which return only row Txn2, Txn5( because all other transaction has atleast one Fail or Success transaction). Also, tried using .distinct() but that didn't help. -
Django fixtures many to many natural keys

django formsets & jquery : execute jquery on added formsets
Let's say I have the following formset. {% for form in formset %} <tr style="border:1px solid black;" id="{{ form.prefix }}-row" class="dynamic-form" > <td{% if forloop.first %} class="" {% endif %}></td> {% render_field form.choicefield1 class="form-control" %}{{form.typeTiers.errors}} </td> <td> {% render_field form.choicefield2 class="form-control" %}{{form.tiers1.errors}} </td> <td>{% render_field form.choicefield3 class="form-control" %}{{form.numfacture1.errors}} </td> </tr> {% endfor %} <td><input type="submit" name="ajoutligne" value="Ajouter une ligne" class="btn btn-primary" id="add-row" style="background-color: #8C1944; border-color: #8C1944; float:right;margin: 5px;" onclick="test()"></td></tr> the forms are added using dynamic-formset.js , which I call in the code bellow to create a new form when clicking on my button : $(function () { $('#add-row').click(function() { addForm(this, 'form'); }); }) and I need to applay jquery function on every row I add in my formset. That's why I created the function test called in onclickfunction: var jax= -1; function test(){ jax =jax+1; alert("hello"); alert($('#id_form-'+jax+'-typeTiers').attr('name')); //for(var i=0;i<) $("#id_form-"+jax+"-typeTiers").change(function () { alert($('#id_form-'+jax+'-typeTiers').attr('name')); x="<option>5</option>"; y="<option>0</option>"; $("#id_form-"+jax+"-tiers").html(x); $("#id_form-"+jax+"-numfacture").html(y); }); } what I need is to make my rows independent of each other, so if I change the field1 in my first row, only the second field in the same row changes, without affecting the other rows. however I have two problems : The first : when I load the page in … -
Django: How to override methods
In my Django app I have to override methods sometimes. My question is if there is something like a "best practice" in how to override a method. Example: In my project I have the following class. class AuthorCreate(CreateView): model = Author form_class = AuthorForm template_name = 'app/create_author.html' def form_valid(self, form): self.object = form.save(commit=False) self.object.creator = self.request.user self.object.save() return super().form_valid(form) So here I have overridden the form_valid() method. It works and I think it's correct. However, is that good practice or not, e.g. I see something like this often: def overridden_method(self, *args, **kwargs): #Some logic here pass So, should have I done it this way? def form_valid(self, form, *args, **kwargs): self.object = form.save(commit=False) self.object.creator = self.request.user self.object.save() return super().form_valid(form) So my question is basically WHEN I should use WHICH "template" for overriding methods or WHEN not to use some specific form. I'd be glad about some detailed/explained best practices. Thanks a lot! -

How to make a file export in a Django FormView?
I'm strugling with overriding the right methods in a Django CBV FormView. The purpose is a to have a view with a simple form, and use the data of this form to generate an Excel export, and make the user download it. Here is what I have so far: class FinancesReportsView(PermissionRequiredCanHandleFinancialReports, FormMessagesMixin, FormView): form_class = DateRangeForm form_valid_message = MSG_EXPORT_OK form_invalid_message = MSG_EXPORT_KO template_name = 'finances/financial_exports.html' success_url = reverse_lazy('bo:financial-reports') def form_valid(self, form): start = form.cleaned_data['start'] end = form.cleaned_data['end'] # Create Excel filename = 'report.xlsx' workbook = xlsxwriter.Workbook(filename) worksheet = workbook.add_worksheet() worksheet.write('A1', start) worksheet.write('A2', end) workbook.close() # Response Headers XLSX_CONTENT_TYPE = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" CONTENT_DISPOSITION = f'attachment; filename="{filename}"' response = HttpResponse(content_type=XLSX_CONTENT_TYPE) response['Content-Disposition'] = CONTENT_DISPOSITION return super().form_valid(form) This obviously does not work, because the return of super().valid_form will bypass the response modifications made earlier. Should I override another method? Any simple code sample would be very appreciated. Thanks. -

How to split one app to two apps in Django?
I made an app(first app) with Django following a tutorial. And I finally completed a web server with AWS EC2, nginx, uwsgi, mySQL, and Django. Then I tried to make a new app(second app). But I found that I put account information(user model) in first app's model.py. Furthermore, I added something like notification functions in first app's model and view etc... I want to make new app with first app's account and notification, but I am not sure it's possible to split one app to two apps. I'd like to make a site(project) have three apps which are account apps(including user model, notification, etc.), first app, and second app. Then, I thought second app can use user info like first app. (Is there any better way?) I just have a questions, how can I split account app from first app without any data loss. Actually I afraid that if I make a problem, it's very hard to restore it. (model, view, url, ...)
