I have a Django project, in which one of my views is displaying a number of tables based on information stored in the database. The view is defined as follows:
def pipeline(request):
...
tables = []
def make_table(detailed_status, projects, status_view=False, first_table=False):
...
table_context_map = {
Project.ds2: {'fields': [['date added',1], ['site visit date',1], ['initial exc VAT',1]]},
...
# Similar lines to populate the tables with data from the database
...
}
table_context = table_context_map[detailed_status]
...
table_context['fields'] = [['project name',1], ['town',1], ['postcode',1], ['contact name',1]] + table_context['fields']
table = render_to_string('.../....html', table_context)
...
return render(request, 'abc.html', context)
What I'd like to do, is at a column to each table created by this view, and insert an 'autonumber' in that column for every row in the table. The tables will be populated dynamically, based on a database query whenever the view is run and the webpage loaded, I just want to number the list of items in each table as it's created.
How would I do this? I am knew to Python Django, so any help or guidance would be much appreciated.
Edit
The part of the HTML that is currently displaying these tables in the webpage looks like this:
<div class="content">
{% block tables %}
{% for table in tables %}
{# Only shows table headers on first table (css first of type on multisection thead) #}
{{table}}
{% endfor %}
{% endblock tables %}
</div>
Edit
The HTML for the file passed into the render_to_string(...) view has the following structure:
{% load getters money_handling staticfiles utilities %}
{% if projects %}
<div class="table-container m-t-lg">
<table class="multisection pipeline left">

Probaly forloop.counter is what you are looking for.
Just use it in your template like this:
<ul>
{% for data in data_list %}
<li>{{ forloop.counter }}</li>
{% endfor %}
</ul>
As for your file hope my modifications will work (marked it with your username):
{% load getters money_handling staticfiles utilities %}
{% if projects %}
<div class="table-container m-t-lg">
<table class="multisection pipeline left">
<tr class="sub-summary">

{% if total_i %}<th>Initial exc VAT: {{total_i|money:"£"}}</th>{% endif %}
{% if total_u %}<th>Latest exc VAT: {{total_u|money:"£"}}</th>{% else %}
<th></th>
{% endif %}
</tr>
</table>
<table class="multisection pipeline left m-b-xl">

{% for field in fields %}

I am customizing django admin template.
I can successfully remove button like (+add model) or some filter by changing overriding change_list_results.html and change_list.html
but now I want to customize each rows of the model to off the link.(I don't want to let the user go each rows editing page.)
I am checking change_list_result.html
{% load i18n static %}
{% if result_hidden_fields %}
<div class="hiddenfields">{# DIV for HTML validation #}
{% for item in result_hidden_fields %}{{ item }}{% endfor %}
</div>
{% endif %}
{% if results %}
<div class="results">
<table id="result_list">
<thead>
<tr>
{% for header in result_headers %}
<th scope="col" {{ header.class_attrib }}>
{% if header.sortable %}
{% if header.sort_priority > 0 %}
<div class="sortoptions">
<a class="sortremove" href="{{ header.url_remove }}" title="{% trans "Remove from sorting" %}"></a>
{% if num_sorted_fields > 1 %}<span class="sortpriority" title="{% blocktrans with priority_number=header.sort_priority %}Sorting priority: {{ priority_number }}{% endblocktrans %}">{{ header.sort_priority }}</span>{% endif %}
</div>
{% endif %}
{% endif %}
<div class="text">{% if header.sortable %}{{ header.text|capfirst }}{% else %}<span>{{ header.text|capfirst }}</span>{% endif %}</div>
<div class="clear"></div>
</th>{% endfor %}
</tr>
</thead>
<tbody>
{% for result in results %}
{% if result.form and result.form.non_field_errors %}
<tr><td colspan="{{ result|length }}">{{ result.form.non_field_errors }}</td></tr>
{% endif %}
<tr class="{% cycle 'row1' 'row2' %}">{% for item in result %}{{ item }}{% endfor %}</tr>
{% endfor %}
</tbody>
</table>
</div>
{% endif %}
and found that <tr class="{% cycle 'row1' 'row2' %}">{% for item in result %}{{ item }}{% endfor %}</tr> out the each row.
However how can I customize each item ???
Thanks for your any help.
In django 1.7+, you can remove the links from the list from the admin model:
class UsersAdmin(admin.ModelAdmin):
list_display_links = None
However, know that this will only remove the link - it will not prevent from users getting into the view/edit page of each row if they can come up with the relevant url. For that, you'll also need to handle that view as well.
See some of these discussions here: https://stackoverflow.com/a/5837386/3121897
This is my code:
<!-- Loop thru Table Macro begins-->
{% macro loopThruTable(currentParent, prod)%}
<li> {{prod.category_name}} </li>
{% set currentParent = prod.id %}
{{ checkParent(currentParent) }}
<ul>
<table>
<tr>
<th>Service</th>
<th>Price</th>
</tr>
{{ checkParentService(currentParent)}}
</table>
</ul>
{% endmacro %}
<!-- Loop thru Table Macro ends-->
<!-- CheckParent Macro begin-->
{% macro checkParent(currentParent) %}
{% for prod in myProd %}
{% if prod.parent_category_id == currentParent %}
<ul>
{{ loopThruTable(currentParent, prod) }}
</ul>
{% endif %}
{% endfor %}
{% endmacro %}
<!-- checkParent Macro Ends-->
<!-- CheckParentService Macro begin-->
{% macro checkParentService(currentParent) %}
{% for serv in myServ %}
{% if serv.parent_category_id == currentParent %}
<tr>
{{ loopThruTableService(currentParent, serv.name) }}
{{ loopThruTableService(currentParent, serv.price) }}
</tr>
{% endif %}
{% endfor %}
{% endmacro %}
<!-- checkParent Macro Ends-->
<!-- Loop thru Table Macro begins-->
{% macro loopThruTableService(currentParent, blah) %}
<td>{{blah}}</td>
{% endmacro %}
<!-- Loop thru Table Macro ends-->
{% extends 'admin/master.html' %}
{% block body %}
<ul>
{% set parent = 0 %}
{{ checkParent(parent) }}
</ul>
{% endblock %}
for all intents and purposes it is running mostly correctly, but it is adding an extra table at the end of each loop.
enter image description here
as you can see in the bottom, there's a "ServicePrice" that is separating each category.
enter image description here
here's another example. I know it has to do with my loops, but as far as jinja2 is concerned, I don't know if there's a method that exists where i check if the parent just 'exists' in my object.
Thanks,
I figured it out.
I had to add one extra for loop and if statement in the loopThruTable Macro.
It now looks like this:
{% macro loopThruTable(currentParent, prod)%}
<li> {{prod.category_name}} </li>
{% set currentParent = prod.id %}
{{ checkParent(currentParent) }}
{% for serv in myServ %}
{% if serv.parent_category_id == currentParent %}
<table>
<tr>
<th>Service</th>
<th>Price</th>
</tr>
{{ checkParentService(currentParent)}}
</table>
{% endif %}
{% endfor %}
{% endmacro %}
I'm still not entirely sure why that works. But it works.
I have a Django site that uses the below template to render a crispy-forms model formset. Using django-debug-toolbar, I gathered that the include tags are rendering the bootstrap4 templates many, many times. I think this is what is killing my performance (i.e. 3-4 minutes to load an inline formset with 100 forms in it)
How should I replace the include tags to avoid the duplicate rendering? Should I use extend somehow?
I can replace the include tags with the actual html from the bootstrap4 crispy-forms templates, but those templates have nested templates as well. That creates an exercising of building a master crispy-forms template that includes everything...which seems like the wrong way to go about this. In addition, I tried replace the bootstrap4/field.html include tag with the actual html, and field.html was still duplicated, and the data lost it's table structure because of the loss of with tag='td'.
{% load crispy_forms_tags %}
{% load crispy_forms_utils %}
{% load crispy_forms_field %}
{% specialspaceless %}
{% if formset_tag %}
<form {{ flat_attrs|safe }} method="{{ form_method }}" {% if formset.is_multipart %} enctype="multipart/form-data"{% endif %}>
{% endif %}
{% if formset_method|lower == 'post' and not disable_csrf %}
{% csrf_token %}
{% endif %}
<div>
{{ formset.management_form|crispy }}
</div>
<div class='table-responsive'>
<table{% if form_id %} id="{{ form_id }}_table"{% endif%} class="table table-hover table-sm" id='dispositionTable'>
<thead>
{% if formset.readonly and not formset.queryset.exists %}
{% else %}
<tr>
{% for field in formset.forms.0 %}
{% if field.label and not field|is_checkbox and not field.is_hidden %}
<th for="{{ field.auto_id }}" class="form-control-label {% if field.field.required %}requiredField{% endif %}">
{{ field.label|safe }}{% if field.field.required %}<span class="asteriskField">*</span>{% endif %}
</th>
{% endif %}
{% endfor %}
</tr>
{% endif %}

<tbody>
{% for form in formset %}
{% if form_show_errors and not form.is_extra %}

and this is currently showing a table with the following column headings:

These column heading are fields belonging to the Class Project, which is defined in the models.py file:

...
ds9 = 120
...
ds13 = 200

employees = models.ManyToManyField(Employee, through=ProjectEmployee)
client = models.ForeignKey(Client, on_delete=models.SET_NULL, null=True, blank=True)
# Several 'def's here, e.g.

...
sm = [person for person in employees if person.role==Role.SM]
...
return{
...
'Site manager': sm[0].employee.first_name if sm else '',
...
}
# Several `#property` definitions here, e.g.
#property
def estimated_compeltion(self):
...
I want to display the Site manager field from the database in the table on the webpage- I tried adding it to the Python code as shown above, but this hasn't made a difference to what is displayed on the webpage, even though that appears to be exactly the same way that all of the other fields from the database are displayed.
What am I missing here? I would expect the Django HTML to display every field that I am telling it to in the Python code, since I am using forloops to get the fields... Why is it that I can't see the 'Site manager' field that I've added to the code in the table on the HTML web page?
In your <td/> you are using project.site_manager
It seems though that your Project model doesn't have such a field, that's why nothing is shown.
Maybe you could create a getter for project_manager in your Project class like so :
def get_site_manager(self):
sm = [person for person in self.assigned.all() if person.role==Role.SM]
return sm[0].employee.first_name if sm else ''
And use it in your template as such :
<td>{{project.get_site_manager()}}</td>
There is a TemplateSyntaxError in horizon. I don not change anything in this model. All of the code is:
