How can I integrate editable tick-boxes for associated WorkCycle data into Django admin without traditional inlines?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I'm working on a Django admin interface that manages projects and their related conditions without using standard inlines. Thanks to @charettes and @KenWhitesell for guiding me this far in my custom admin quest.

Here's my current setup:

I have a Project model and a ProjectObjectiveCondition model linked by a ForeignKey (see the models on Github):

PYTHON
class Project(models.Model): [...] class ProjectObjectiveCondition(models.Model): project = models.ForeignKey(Project, on_delete=models.CASCADE)

With a custom inline admin template (available on Github), the inlines display grouped by Objective and Level using repeated {% regroup %} calls. For example, the rendered inline looks like this:

This groups data as follows:

  • Objective: Agreeableness
    • Level: Started
      • Condition: Speaks pleasantly
      • Condition: Doesn’t shout
    • Level: First results
      • Condition: Accepts thanks with grace
    • Level: Mature results
      • Condition: Apologises with sincerity
  • Objective: Colourfulness
    • Level: Started
      • Condition: Has blue
      • … and so on

Date/commitment columns are also shown alongside columns for WorkCycle (instances of the WorkCycle class). They indicate whether a commitment has been made for this project to reach a certain level in a given cycle (year).

What I want to achieve is replacing these static date/commitment columns with editable tick-boxes right next to their associated Objective and Level within the inline display.

I already have another inline, LevelCommitmentInline, that lets me edit those True/False values for the model, but I don’t want a separate long list. I want each tick-box to appear next to its corresponding Objective, Level, and under the date columns in the same view.

My thinking is that I might need to generate multiple forms—one for each Objective/Level pair of the Project for each WorkCycle—and then attach these forms to something since the Objective and Level in the template aren’t coming from the form, but are extracted via the {% regroup %} tag.

How can I generate, attach, and display these multiple forms in the admin interface so that each tick-box aligns with its corresponding Objective and Level under the correct date columns? Any bright ideas or guidance is appreciated.

Custom Django Admin Interface with Grouped Forms

Based on your complex admin interface requirements, you'll need to create a custom solution that combines your regrouped display with editable form fields. Here's an approach to integrate those tick-boxes alongside your grouped conditions:

1. Create Custom ModelAdmin with Form Preparation

You'll need to override the get_form method to prepare your custom form with the necessary data:

PYTHON
class ProjectAdmin(admin.ModelAdmin): def get_form(self, request, obj=None, **kwargs): # Get the base form form = super().get_form(request, obj, **kwargs) if obj: # Only for existing projects # Fetch all related data objective_conditions = ProjectObjectiveCondition.objects.filter(project=obj) work_cycles = WorkCycle.objects.all() # Or filter as needed # Prepare data for template self.prepared_data = self.prepare_grouped_data(objective_conditions, work_cycles, obj) return form def prepare_grouped_data(self, conditions, work_cycles, project): # Group conditions by objective and level # Also attach commitment data for each work cycle grouped_data = {} # Your grouping logic here # ... return grouped_data def change_view(self, request, object_id, form_url='', extra_context=None): extra_context = extra_context or {} if hasattr(self, 'prepared_data'): extra_context['prepared_data'] = self.prepared_data extra_context['work_cycles'] = WorkCycle.objects.all() # Or filter as needed return super().change_view(request, object_id, form_url, extra_context)

2. Create a Custom Template

You'll need to modify your template to include form fields for each commitment:

HTML
{% extends "admin/change_form.html" %} {% load admin_urls %} {% block field_sets %} {{ block.super }} {# Your custom grouped display #} <div class="grouped-conditions"> {% for objective, levels in prepared_data.items %} <div class="objective-group"> <h3>{{ objective.name }}</h3> {% for level, conditions in levels.items %} <div class="level-group"> <h4>{{ level.name }}</h4> {# Commitment checkboxes for this level #} <div class="commitment-checkboxes"> {% for cycle in work_cycles %} <div class="cycle-checkbox"> <label>{{ cycle.year }}</label> <input type="checkbox" name="commitment_{{ objective.id }}_{{ level.id }}_{{ cycle.id }}" {% if level.commitments|get_item:cycle.id %}checked{% endif %}> </div> {% endfor %} </div> {# Conditions list #} <ul class="conditions-list"> {% for condition in conditions %} <li>{{ condition.text }}</li> {% endfor %} </ul> </div> {% endfor %} </div> {% endfor %} </div> {% endblock %}

3. Process the Form Submission

You'll need to override the save_model method to handle your custom form fields:

PYTHON
def save_model(self, request, obj, form, change): super().save_model(request, obj, form, change) # Process commitment checkboxes if change: # Only for existing objects for key, value in request.POST.items(): if key.startswith('commitment_'): # Parse the field name to get IDs _, objective_id, level_id, cycle_id = key.split('_') # Find or create the commitment commitment, created = LevelCommitment.objects.get_or_create( project=obj, objective_id=objective_id, level_id=level_id, work_cycle_id=cycle_id, defaults={'is_committed': value == 'on'} ) if not created: # Update existing commitment commitment.is_committed = value == 'on' commitment.save()

4. Add Custom JavaScript for Better UX

You might want to add some JavaScript to enhance the user experience:

JAVASCRIPT
// Add this to your admin.js or inline in the template document.addEventListener('DOMContentLoaded', function() { // Add any interactive behaviors for your checkboxes const checkboxes = document.querySelectorAll('.commitment-checkboxes input[type="checkbox"]'); checkboxes.forEach(checkbox => { checkbox.addEventListener('change', function() { // Optional: Add visual feedback when changed this.closest('.cycle-checkbox').classList.add('changed'); }); }); });

Alternative Approach: Custom Formsets

If the above approach becomes too complex, you might consider using Django's formset factory to create multiple forms:

PYTHON
from django.forms import formset_factory, Form, BooleanField class CommitmentForm(Form): is_committed = BooleanField(required=False) # Hidden fields to identify the relationship objective_id = forms.IntegerField(widget=forms.HiddenInput()) level_id = forms.IntegerField(widget=forms.HiddenInput()) cycle_id = forms.IntegerField(widget=forms.HiddenInput()) # In your ModelAdmin def get_formsets_with_inlines(self, request, obj=None): # First yield the standard formsets/inlines yield from super().get_formsets_with_inlines(request, obj) if obj: # Create a custom formset for commitments CommitmentFormSet = formset_factory(CommitmentForm, extra=0) # Prepare initial data initial_data = [] # ... populate initial_data based on your objectives, levels, and cycles formset = CommitmentFormSet(initial=initial_data, prefix='commitments') # You'll need to handle this formset in your template and in save_model yield formset, None # None instead of an inline

This is a complex customization that will require careful implementation and testing. You might need to adjust the approach based on your specific model structure and requirements.
