Hi! I hope the following will help future django developers.
Scenario:
We need a form that allows the user to *add *and *remove* referees from a
resume: see (rough) snippet below:
(using materializecss)
<div class="row">
<div class="input-field col s6">
<input id="ref_name" type="text" class="validate">
<label for="ref_name">Reference Name</label>
</div>
<div class="input-field col s6">
<input id="ref_position" type="text" class="validate">
<label for="ref_position">Current Position</label>
</div>
<div class="row">
<a class="btn-floating btn-large waves-effect waves-light red"
style="text-align:center;"><i class="material-icons">clear</i></a> <!--
for removing the referee -->
</div>
</div>
<div class="row">
<div class="col s12">
<center>
<a class="btn-floating btn-large waves-effect waves-light red"
style="text-align:center;"><i class="material-icons">add</i></a>
</center>
</div>
</div>
We have a resume model, and referees model with a many-to-many relationship
like so:
class Resume(models.Model):
first_name = models.CharField(max_length=250)
last_name = models.CharField(max_length=250)
...
class Referees(models.Model):
resume = models.ForiegnKey(Resume, on_delete=CASCADE)
name = models.CharField(max_length=250)
position = models.CharField(max_length=250)
What is the best way to achieve this?
questions:
- I'm assuming when user hits 'add', we'll need to clone a copy of the
two input fields ('reference name' and 'current position'), and append it
to the form? is using the java-script clone method best practice?
- Is it best to create a new instance of the referee model each time a
user hits "add", or create them all at once when the submit the form. (hit
save)
- When the user returns to edit view, the form will need to repopulate
with all the new referees they added - what would be the best way to do
this?
Note we're not using react or angular. Just pain old html / js / ajax.
All advice, solutions, suggestions most appreciated.
Cheers!
