Is it possible to configure a link to open a page that contains an iframe, and have that iframe query an URL?
I am setting up a registration confirmation email system. The sign-up process usually takes place on my platform, and upon receiving the confirmation email, the link redirects to the same website the new user has signed-up on. But the sign-up page I'm having trouble with is contained in an iframe on a website that I have no control over. I can only change what's inside of the iframe. I would need the link sent through email to redirect to the page that contains the aforementionned iframe, while still activating the user in the iframe. I work with django templates. I can change the body of the email, the registration page and the confirmation page, that's about it. -
Django with Datatables Edits Database in Front End
I am trying to build a page that user can select and edit multiple/all rows. I am able to replicate the check button for each row and select all button according to https://www.gyrocode.com/projects/jquery-datatables-checkboxes/. But I am unable to replicate the submit button. My guess is because the example uses ajax. I use pandas data frame. I have limit knowledge to html and js, so what I did is basically try to understand what the code is doing.. python code def test(request): df = pd.DataFrame(list(Test.objects.all().values())) var1 = df.to_html(justify='center', index=False) var1 = re.sub('table border="1" class="dataframe"', 'table id="example" class="table table-striped table-bordered" style="width:100%"', var1) return render(request, 'main/test.html', {'dfs': var1}) html code <form id="frm-example"> {{dfs|safe}} <p> <button>Submit</button> </p> <p> <b>Selected rows data:</b><br> <pre id="example-console-rows"></pre> </p> <p> <b>Form data as submitted to the server:</b><br> <pre id="example-console-form"></pre> </p> </form> <script src="https://gyrocode.github.io/jquery-datatables-checkboxes/1.2.11/js/dataTables.checkboxes.min.js"></script> js code $(document).ready(function (){ var table = $('#example').DataTable({ paging:false, 'columnDefs': [ { 'className': 'dt-body-center', 'targets': 0, 'checkboxes': { 'selectRow': true } } ], 'select': { 'style': 'multi' }, 'order': [[1, 'asc']] }); // Handle form submission event $('#frm-example').on('button', function(e){ var form = this; var rows_selected = table.column(0).checkboxes.selected(); // Iterate over all selected checkboxes $.each(rows_selected, function(index, rowId){ // Create a hidden element $(form).append( $('<input>') .attr('type', 'hidden') .attr('name', … -
Use custom `Manager` for "default values" creation and fetching
I have and Employee model and an EmployeeType model, with Employee having an attribute called Employee.employee_type which is of type EmployeeType. Currently on the creation of a client, we run something to create "default" values for the EmployeeType. Right now, that logic is in a method within the module that handles a new client being created... but I was thinking a better place for this would be to be with the EmployeeType model. My question is - would it be appropriate to make a custom Manager attribute on the EmployeeType that does the creation and/or fetching of these default types? See the following for what I believe I am trying to accomplish: class DefaultValueEmployeeTypeManager(models.Manager): def get_or_create_default_values(self): first_type = self.model.objects.get_or_create(name='First Type') second_type = self.model.objects.get_or_create(name='Second Type') third_type = self.model.objects.get_or_create(name='Third Type') return (first_type, second_type, third_type) class Employee(models.Model): first_name = models.CharField(max_length=255) last_name = models.CharField(max_length=255) defaults = DefaultValueEmployeeTypeManager() # Code in another file, handling the setup of a new client from models import EmployeeType def create_new_client(client): # make sure the default values are there EmployeeType.defaults.get_or_create_default_values() My question is whether or not this is acceptable/expected behavior for a Manager object to handle? Or should this just be some sort of @classmethod (or similar) on the EmployeeType … -

How to make all the delete href tags make work with java scripts if clicked in Django
I have written a java script for the conformation box before deleting the comments. If user clicks delete, it should pop the box for delete conformation. If i have series of comments of same user, as i am printing the comments in loop the java script logic is staying with the first delete comment itself until i delete it. If i say no, and try to delete second comment, the java script logic is not function. Can any one help me with this issue. Should i need to place the java script logic some where else in the code. Does that recognize? <div class="container"> <h2 class="text-center">User Comments</h2> {% for comment in comments%} <p class="text-secondary text-center">{{ comment.created }}</p> <p> {{ comment.body }} </p> {% if comment.user == request.user.username %} <a class="btn btn-secondary btn-sm mt-1 mb-1" href="{% url 'comment-update' comment.id %}">Update Comment</a> <a class="btn btn-danger btn-sm mt-1 mb-1" id="delete-object" >Delete Comment <script type="text/javascript"> document.getElementById("delete-object").onclick = function(){ if (confirm('Delete the comment')){ alert('hi'); #Link to delete comment}} </script> {% endif %} -
Can django @login_required be used on APIs used by a mobile app?
We're using django-notifications-hq to provide users with persistent notifications in our app. Until recently, they lived only in the web app, however now we want to show the notifications in the mobile app as well. Also, our server is set up with CSRF. All the endpoints provided by django-notifications-hq use @login_required annotation to verify that user is authenticated. However, when we're trying to call any of those endpoints from our mobile app, we get 403 response. To be specific, the first OPTIONS request returnd 200, but then the following request for those APIs always results in 403. This is not a problem when we're using i.e. django-rest-framework's permissions.IsAuthenticated. The 403 returns this in the response: <h1>Forbidden <span>(403)</span></h1> <p>CSRF verification failed. Request aborted.</p> <p>You are seeing this message because this site requires a CSRF cookie when submitting forms. This cookie is required for security reasons, to ensure that your browser is not being hijacked by third parties.</p> <p>If you have configured your browser to disable cookies, please re-enable them, at least for this site, or for &#39;same-origin&#39; requests.</p> Suggesting it's a CSRF problem, even though mobile app obviously doesn't provide cookies in their requests (it's token-based authorization).

Using a base.html file but modifying more than just the body
First of all, I have no problems with my code. This question is more of a "Is this possible and if so/not what is the right way of doing it ?" I have a website where every page has the same look, the differences between them are as follows: The homepage has an interactive leaflet map (javascript) The titles vary on every page The elements in the head tags change from one page to another but not always The background image doesn't change Within the body tag, I have a div tag containing a page footer common to all pages What I would like to know is if it is possible to use a base.html template for these pages knowing the above constraints and also, if it is, how I would go about modifying the said pages to do so. As I said, the code isn't really an issue here but for clarity and for you to be able to see what changes from one page to another, here is the Github repository for the project.

How to filter queryset for serializing a nested serializer using instance in django rest framework?

How do I do this? P.S: Please don't tell me to use ModelSerializer or SerializerMethodField because options is not directly related to Question and the options field needs to be writable. -
Cannot access admin panel after setting up django-oauth-toolkit
I had a pet-api (testing api) without authentication. I'm trying to learn how to implement oath2 to add security to my app. I'd like to access the models of my app through a request call using the API but also through the Django Admin Panel. I'm following this tutorial: https://medium.com/@halfspring/guide-to-an-oauth2-api-with-django-6ba66a31d6d for setting up: django-oauth-toolkit Tutorial says I should add this code to settings: AUTHENTICATION_BACKENDS = ( 'django.contrib.auth.backends.ModelBackend' # To keep the Browsable API 'oauth2_provider.backends.OAuth2Backend', ) But when I run server, and try to access /admin, I get: ModuleNotFoundError at /admin/login/ No module named 'django.contrib.auth.backends.ModelBackendoauth2_provider'; 'django.contrib.auth.backends' is not a package If I comment: # 'django.contrib.auth.backends.ModelBackendoauth2_provider'; I can access the interface for the login, but says my user or password are wrong (they are not).

How to set environment variables for different domains in one docker-compose file

Obtaining host url of sftp server from a docker container
I am running django project in docker container. I have a sftp server running on another container, and wish to sftp into it from web container.

Two generated images in a django page... one never loads
This is a bizarre one. I have a view which creates two png files in the static directory for my django app, then serves a template which shows them. One of the images loads correctly; the other never loads (but the browser is waiting for it). It appears to be random whether it is the first or second image. Things I have verified: - Both images exist in the static directory and look fine from an image browser. - The URL to the images appear to be correct. Here is the view which uses matplotlib to create two images in the static/ directory: nii_image_list = [] for desired_file, desired_tag in desired_image_list: if not os.path.isfile(desired_file): continue desired_name = scan_name + "_" + desired_tag nii_image_list.append((save_nii_preview_to_static_file(desired_file, desired_name), desired_tag)) plt.clf()The # print(nii_image_list) template = loader.get_template('server/scan_deep.html') context = { 'scan': scan, 'nii_image_list': nii_image_list } return HttpResponse(template.render(context, request)) def show_nii(filename): nii = nib.load(filename) dimensions = nii.header.get_data_shape() data = nii.get_dTheata() slice_0 = data[round(dimensions[0] * 0.5), :, :] slice_1 = data[:, round(dimensions[1] * 0.5), :] slice_2 = data[:, :, round(dimensions[2] * 0.5)] show_slices([slice_0, slice_1, slice_2]) def save_nii_preview_to_static_file(nii_filename, name): filename = os.getcwd() + "/static/" + name.replace(' ', '') + ".png" html_static_filename = name.replace(' ', '') + ".png" show_nii(nii_filename) plt.savefig(filename) … -

Django app only runs on https even after removing SECURE_HSTS_SECONDS setting
I had set SECURE_HSTS_SECONDS=3600 in my settings.py in order to improve my app security. It has been more than 1 hour since I did that and I have removed the line now but still whenever I execute python manage.py runserver with DEBUG = False on http://127.0.0.1:8000/ it gives me Server Error (500). The browser console displays the following message: The character encoding of the HTML document was not declared. The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the page must be declared in the document or in the transfer protocol. Please Note that my app runs perfectly when: DEBUG = True , in which case the app runs on my localhost as expected. I open my app via the HTTPS URL with DEBUG = False on my Heroku domain. I read the warning in the Django Docs which states: Setting this incorrectly can irreversibly (for some time) break your site. And the the following suggestion from the Docs: When enabling HSTS, it’s a good idea to first use a small value for testing, for example, SECURE_HSTS_SECONDS = 3600 for one hour. Each time …
