Can I automatically add a filter to a MongoEngine query in Django?
I'm using MongoEngine with Django and I want to add a default filter on all queries that retrieve data, as well as some further logging. MongoEngine has signals, but does not appear to have any signal for pre-query. Am I missing something or can anyone recommend an elegant solution? -
Can't get Django-Simple-Captcha to work, posts even when using wrong captcha
I think this is a simple issue to solve, but I've been trying for a couple of hours now and I think that my View file is messed up. The captcha shows up on my page, but when i create a post and fill out the completely wrong captcha it get sent and updated anyway. My views-file: def discussions(request): posts = Post.objects.filter(created__lte=timezone.now()).order_by('-created') if request.method == 'POST': captcha = CaptchaTestModelForm(request.POST) if captcha.is_valid(): human = True else: captcha = CaptchaTestModelForm() if request.method == 'POST': form = PostForm(request.POST, request.FILES) if form.is_valid(): post = form.save(commit=False) post.created = timezone.now() post.save() return redirect('discussions') else: form = PostForm() captcha = CaptchaTestModelForm() -
Dynamically Build Q Filter in Django, with AND and OR Operators?
I have a database table of articles which includes a field link, which is the link to the article. I'd like to filter for articles in a given date range, that come from domains in a given list. I've got a string array like this: domain_names = [ 'domain_name_1', 'domain_name_2', 'domain_name_3', 'domain_name_4', ] ...and I have a filter like this which works: data = (myArticles.objects .filter(Q(creation_datetime__range=[from_date, to_date]) & (Q(link__contains=domain_names[0]) | Q(link__contains=domain_names[1]) | Q(link__contains=domain_names[2]) | Q(link__contains=domain_names[3]))) ) I'd like to dynamically build the filter, so that if an object is added to or removed from the domain_names list, the filter will dynamically update. I've tried this: q_object = Q() for name in domain_names: q_object.add(Q(link__contains=name), Q.OR) q_object = q_object.add(Q(creation_datetime__range=[from_date, to_date]), Q.AND) ...but I'm getting back all the objects in the date range, and the filter that's supposed to be filtering on domain_names isn't doing anything yet. What's the correct way to dynamically build a Q filter in this case? -
Django migrate from sqlite3 to mysql
I am trying to migrate my Django app from SQLite3 to MySql. I took following steps Configured a new empty database on MySql. I did not create any tables because I assumed that the tables will be created by the migrate command. Created a new user who has access to this database CREATE USER 'djangouser'@'%' IDENTIFIED WITH mysql_native_password BY 'password';GRANT ALL ON djangoappdb.* TO 'djangouser'@'%'; Stopped the server Dumped all the data to a file using python3 manage.py dumpdata > currData Deleted all the existing migrations reran python3 manage.py makemigrations. This step created a single new migration file Changed the setting.py file to use MySql and djangoappdb with correct username and password. ran python3 manage.py migrate command.

Detect Every Third Loop in a HTML Forloop - HTML - Django
I have a website and on one page there is repeating information from a for loop that is made to print. The problem is that every item in the forloop is about 10 lines of text. When I go to print, the 10 lines of text will sometimes break between pages. I need them to stay together no matter what and I have tried "page-break-inside: avoid;" but I can't get it to work. It is somewhat irrelevant however because I need to make sure every page only has three blocks on it because 4 already overdose the margins. My plan is to loop through the blocks just fine and detect every third loop and add extra spacing below it to get it to go to the next page. Question: How do I detect every third loop in my html forloop? {% for post in filter.qs %} {% if forloop.first %} <div style="position:relative; top: -12px; left: -2px; margin-bottom: 180px;"> <div style="position:absolute;left:21.79px;top:435.49px" class="cls_0030"><span class="cls_0030">{%if post.department%} {{post.department}}{%endif%}</span></div> <div style="position:absolute;left:248.82px;top:435.54px" class="cls_014"><span class="cls_014">Inspection #</span></div> <div style="position:absolute;left:355.58px;top:435.52px" class="cls_013"><span class="cls_013">{{ post.count_building }}</span></div> <div style="position:absolute;left:21.70px;top:453.54px" class="cls_014"><span class="cls_014">Inspection Date</span></div> <div style="position:absolute;left:96.52px;top:453.52px" class="cls_013"><span class="cls_013">{%if post.date%}{{post.date}}{%endif%}</span></div> <div style="position:absolute;left:248.82px;top:453.54px" class="cls_014"><span class="cls_014">Inspection Time</span></div> <div style="position:absolute;left:338.10px;top:453.49px" class="cls_008"><span class="cls_008">{%if post.time%}{{post.time}}{%endif%}</span></div> <div style="position:absolute;left:21.70px;top:471.54px" class="cls_014"><span class="cls_014">Floor(s)</span></div> <div … -

How do I download a Django webpage into a PDF with all the css when user clicks "PDF" button? (Exactly how it looks, into a PDF)
I have tried using multiple technologies like weasyprint and reportlab but have not been able to make the webpage that the user is seeing into a pdf. I have read the documentation but maybe I am missing steps but I eventually want to take the exact page they are looking at and when the press the "PDF" button, it downloads the entire web page into a PDF with all the css and everything. The webpage does contain heatmap charts made with plotly, at times the webpage can have 2 charts or sometimes up to 20 charts. I currently just call the 'window.print()' function but it cuts off the charts and I was hoping that if I utilize weasyprint or a similar technology then I can have the charts be displayed correctly. Thank you in advance. -
Is it possible to define only a reference to a text in django templates, and change it later?
First of all, I am sorry for my English! If I have a multi-language app, in one button for registration I would do something like this: <button>{% trans 'Register now!' %}</button> Then I have to generate the dictionary for translations and then, a translator of my team will assign the value for "Register now". Right? #: templates/file.html:30 msgid "Register now!" msgstr "Regístrate ahora!" But what happens if the texts are not yet defined, or are going to change? Is it possible with a Django plugin, to just define a reference to a given text of a component in my HTML and then someone from my team will fill in the text and generate the translations? Something like: <button>{% text 'button_text_for_registration' %}</button> // Maybe this will change Rosetta adds an interface for translations, but it is not possible to change the default dictionary text. Is there a plugin that does this? Or what would be the best way to manage this dynamic content? -
Django model method not making changes to object
I have a method on my model to change an object from being published to unpublished. The redirect works alright but in my database, nothing happens.

django shell - some querysets are empty in the shell but they shouldn't be
I am using the django shell to look at some querysets. I am able to retrieve all of my Student objects with .all() but if I then try to retrieve one object with .get() or filter on a field, I'm getting empty returns. The project seems to run ok on the browser (I'm still in the progress of writing all my tests but functionally it is working). I am able to successfully use get() or filter on a field with my Objectivemodel.

Django: how to solve several Foreign key relationship problem?
I'm currently learning Django and making electronic grade book. I am completely stuck after trying everything, but still cannot solve the problem. I will explain in detail and post all the relevant code below. I need to have two url pages "class_students" and "teacher_current". The first page is for the teacher to see the list of students of a certain class. The table on this page has "action" column. In every cell of this column there is View button, so that the teacher could be redirected to "teacher_current" page and see the list of current tasks, given to a certain student. On this page there is a "Mark" column, its cells may contain EITHER mark given to this student with link to another page to update or delete this mark OR "Add mark" link to add mark on another page. Here comes the problem: everything works correctly, except the thing that each mark is related to a Task class via Foreign key and NOT to a Student class. So every student of the same class has the same marks for the same tasks. But it certainly won't do. Here is all my relevant code: 1) views.py models.py urls.py: https://www.codepile.net/pile/qkLKxx6g 2) … -

Is there a way of having variable methods/functions in django?
I would like to be able to create functions to use them as "rules" or conditions. let's say i have a bunch of employees, but to calculate commissions to each one i would like to call a function that calculates the output. there are cases where i would reuse the function between employees but cases too where i would only have a function for a single employee. said function can change in time and must apply for all employees with that function. Example: if employee have more than 3 sales, give him/her 15% of beneficts from all sales: i would create a function like this: output = 0 orders = Order.objects.filter(employee = kwargs.get('employee_id')) if len(orders) < 3: return output for order in orders: output += (order.benefits * 0.15) return output Notes: Should be able to receive parameter in KWARGS as variables and others -
