open another page from html button with the same pk value

Using Django Using the ORM
1

hi all,
I have three concatenated pages
1)

path('admin-view-patient', patientView.admin_view_patient_view,name='admin-view-patient'),

path('update-patient/<int:pk>', patientView.update_patient_view,name='update-patient'),

path('add-patient-note/<int:pk>', patientView.add_patient_note_view,name='add-patient-note'),

the first html file contain

<div class="container">
  <div class="panel panel-primary">
    <div class="panel-heading">
      <h6 class="panel-title">Patient</h6>
    </div>
    <table class="table table-hover" id="dev-table">
      <thead>
        <tr>
          <th>Name</th>
          <th>Address</th>
          <th>Update</th>
        </tr>
      </thead>
      {% for p in patients %}
      <tr>
        <td> {{p.get_name}}</td>
        <td>{{p.address}}</td>
        <td><a class="btn btn-primary btn-xs" href="{% url 'update-patient' p.id  %}"><span class="glyphicon glyphicon-edit"></span></a></td>
      </tr>
      {% endfor %}
    </table>
  </div>
</div>

clicking on UPDATE-PATIENT it open second page with link http://127.0.0.1:8000/update-patient/1

<form method="post" enctype="multipart/form-data">
  {% csrf_token %}
  <div class="container register-form">
    <div class="form">
      <div class="note">
        <p>Update Patient Details</p>
      </div>
      <div class="form-content">
        <div class="row">
          <div class="col-md-6">
            <div class="form-group">
              {% render_field userForm.first_name class="form-control" placeholder="First Name" %}
            </div>
            <div class="form-group">
              {% render_field patientForm.address class="form-control" placeholder="Address" %}
            </div>
          </div>
        </div>
        <button type="submit" class="btnSubmit">Update</button>
      </div>
      <a href="{% url 'add-patient-note' p.id  %}">
        <h6 class="m-b-20">Admit Patient</h6>
      </a>
    </div>
  </div>
</form>

clicking on add-patient-note ADD-PATIENT-NOTE i would like open page with the same patient ID in order to create the note with the foreignkey patient to who associate the note.

the note models.py has the patientNotes:

class PatientsNotes(models.Model):
    patient = models.ForeignKey(Patient,on_delete=models.CASCADE)
    title = models.CharField(max_length=20,default=None)
    body = models.TextField(default=None)
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)
    active = models.BooleanField(default=True)
    
    class Meta:
        ordering = ['created']
        indexes = [
                models.Index(fields=['created']), 
                ]
    def __str__(self):
        return f'Comment by {self.name} on {self.post}'

and forms.py have the note form

class PatientNotesForm(forms.ModelForm):
    class Meta:
        model = models.PatientsNotes
        fields = ['title', 'body']

it is possible?
many thanks in advance

Yes.

What is the problem you are facing when trying to do this?

I don’t know how to pass current pk from page to page. I don’t know basically how to do that. I’m sorry :frowning:

You’re doing it here:

You’re trying to render a value here referenced as p.id. That means that you would have to pass some object into your context, with the key in the context of p and having an attribute named id.

Are you doing that?

Data might be supplied to a view through url segments or form data, but it’s always supplied to the template through the context. Everything being rendered must be put into the context.
