Django DateField

[dtdave]

I have a model that contains a datefield which signifies the start date for a task.

My modelmanager filters the tasks by the start date and the template lists them in the date descending order. Everything is fine with this.

However, now I have been asked to change this so that some projects have a start date of ASAP and others have date.

These then need to be listed in my template with ASAP tasks coming first and then those with a start date coming in descending order.

I am at a loss as to how to achieve this so would welcome any pointers or ideas.

Thanks

Add another field, say asap = model.BooleanField(default=False), sort by asap, date in reverse. The field asap True values will be sorted first, then the asap False will be sorted by date. You may want to ensure asap = False only if date is not None.

Asap field is a boolean. Date field needs to be able to be blank and null.
Then:

tasks = Task.objects.order_by('asap', '-start_date')

Done :)

I wonder if this would work: represent ASAP as a legitimate DateTime value that is, say, 100 years in the future.  Then a simple reverse sort will display all of the ASAP tasks before any others.

This is a hack, and nothing but a hack.  But you could implement it in five minutes.

Many thanks for the help on this. I have implemented the following:

models.py

start_date = models.DateField(null=True, blank=True,)

asap = models.BooleanField(default=False)

I have amend my manager so the order is right on the template.

The template is where I am going wrong.

This what I have started with in my template;

{% if 'job.asap' == 'True' %}

<p>Start Date: {{job.asap}}</p>

{% else %}

<p>Start Date:{{job.start_date}}</p>

{% endif %}

The start dates are listed in the correct date order but any of those tasks with an ASAP start show None as the start date in the template.

I know the answer is probably obvious, but for smoe raeson I cannot fathom it out at the moment.

Again thanks for all the help

{% if job.asap %}
<p>Start Date: {% trans "as soon as possible" %}</p>

{% else %}
<p> Start Date: {{job.start_date}}</p>
{% endif %}
