My Django view is returning a list of dictionaries. This goes to html table through template rendering. Below is my template code,
My list of dictionary looks like below,
Results :
[{ 'name':'x','age': 20}, {'name': 'y','age': 25 }]
<table class="table table-striped" border="1" class="dataframe">
<thead>
<tr style="text-align: center;">
{% for k, v in results.0.items %}
<th>{{ k }}</th>
{% endfor %}
</tr>
</thead>
<tbody>
{% for x in results %}
<tr style="text-align: center;">
{% for y in x %}
<td> {{ x.y }} </td>
{% endfor %}
</tr>
{% endfor %}
</tbody>
</table>
Expected output:
name age
x 20
y 25
But the output is blank.
Please let me know if there is anything wrong with my HTML table template.
You can use items properly in your inner loop just like the outer loop
<div>
<table class="table table-striped" border="1" class="dataframe">
<thead>
<tr style="text-align: center;">
{% for k, v in results.0.items %}
<th>{{ k }}</th>
{% endfor %}
</tr>
</thead>
<tbody>
{% for x in results %}
<tr style="text-align: center;">
{% for i,j in x.items %}
<td> {{ j }} </td>
{% endfor %}
</tr>
{% endfor %}
</tbody>
</table>
</div>

Could someone shed a light to help me to solve this nested list problem in Django template.
I come across a list as such
[['Summary 1 CODE018'], [['Directory/File Name', 'Result']], [[['dir/var1/file1.txt', 'pass'], ['dir/var2/file2.txt', 'pass'], ['dir/var1/file3', 'pass']]], [[['null']]]]
How do I loop the above list so that I can get a table such as the first index is the table title, index1 is the table title and the rest (except when is it null) is the table body? Please take note that the last item could be [[['null']]] or [[['null', 'Info on directory CODEA18']]] which should be skip when null is detected.
Expected table:
Directory/File Name Result
dir/var1/file1.txt pass
dir/var2/file2.txt pass
dir/var3/file3.txt pass
My faulty code as below
<table id="myTable">
{% for list in summary %}
<tr>
<td> {{ list.0 }} </td>
<tbody>
<td> {{ list.0.0 }} </td>
<td> {{ list.0.0.0 }} </td>
</tbody>
</tr>
</table>
You list have 4 items. In that 2nd is Table heading and 3rd is table row.
We need to run 2 loops, one for thead and one for tbody
<table border>
<thead>
<tr>
{% for i in a[1][0] %}
<th>{{i}}</th>
{% endfor %}
</tr>
</thead>
<tbody>
{% for i in a[2][0] %}
<tr>
{% for j in i%}
<td>{{j}}</td>
{% endfor %}
</tr>
{% endfor %}
</tbody>
</table>

I am scraping several sites and I show the data obtained in 6 tables within a django template.
My intention is to persist the data of the tables in postgresql, but I can not realize how to perform that task.
In principle I am trying to save the data from the second table.
For this I have created the models that I show below, as well as a view that is called: registroDivisaArgentina ().
The template is called quotes.html and within it, there are 6 tables.
I have tried to work with a class called: RegisterArgentineValues () within a forms.py file
models.py
class DivisasArgentina(models.Model):
class Meta:
ordering = ['CodigoDA']
CodigoDA = models.CharField(max_length=50, primary_key = True)
Texto_para_Reporte = models.CharField(max_length=70)
def __str__(self):
return '{}'.format(self.Texto_para_Reporte)
class ValoresDivisasArgentina(models.Model):
class Meta:
ordering = ['Dia']
DivisasArgentina = models.ForeignKey(DivisasArgentina, on_delete=models.PROTECT)
Dia = models.DateField(default=date.today)
Hora = models.DateTimeField(default=timezone.now)
Compra = models.FloatField()
Venta = models.FloatField()
Variacion_dia_anterior = models.FloatField()
ClaveComparacion = models.CharField(max_length=1)
def __str__(self):
return '{} - {} - {}'.format(self.DivisasArgentina, self.Dia, self.ClaveComparacion)

I have done some tests, but none has given a favorable result. Someone can tell me how to process the data (in the views and forms) that are in the tables, to be able to store them in my postgres tables ?
I do this kind of task very often, and I've found out that the combination of ScraPy with scrapy-djangoitem is a very good combo to use here.
Good luck!
I got 2 queryset list expired_item and queryset in Django ListView, but I don't know when item is expired(queryset is empty), how to display another list expired_item on frond end, no matter what I changed in abc.html, expired_item won't dispaly, I pasted my code as below:
class ABCListView(ListView):
model = ABC
ordering = ('name', 'skill_course')
context_object_name = 'abcs'
template_name = ''
def get_queryset(self, **kwargs):
# Omitted
......
......
# Omitted
expired_item = list(ABC.objects.filter(pk__in=aa).exclude(pk__in=z))
queryset = Permit.objects.filter(pk__in=z)
return queryset
And my html file of abc.html as below:
{% extends 'base.html' %}
{% block content %}
<nav aria-label="breadcrumb">
</nav>
<h2 class="mb-3">My Items list</h2>
<div class="card">
<table class="table mb-0">
<thead>
<tr>
<th>Name</th>
<th>Department</th>
<th>Status</th>
<th></th>
</tr>

<tbody>
{% for a in abcs %}
<tr>
<td class="align-middle">{{ a.name }}</td>
<td class="align-middle">{{ a.department.get_html_badge }}</td>
<td class="align-middle badge badge-pill badge-danger">{{ a.status }}</td>

{% empty %}
{% endfor %}

Thanks so much for any advice!
I would suggest use a normal django view. This Generic ListView is just created for the use of one list. Just pass both querysets in your context and render your template with that.
You could also use get_context_data() but this would be more or less hacky and not the qay I would recommend.
I am trying to output 2 items for each row. I have 4 items coming from db.
<table>
<tr>
{% for item in items %}
<td>
{{item.name}},{{item.size}}
</td>
{% endfor %}
</tr>
</table>
this is giving me
name1, 23m^2 | name2,20m^2 | name3,15m^2 | name4,10m^2
but i need
name1, 23m^2 | name2,20m^2
name3,15m^2 | name4,10m^2
each row being contained in separate <tr>. I am stuck how to break the loop and assign new row..
Just switch the <tr> and forloop, and also use forloop.counter and divisibleby
Something like this:
{% if items %}
<tr>
{% for item in items %}
<td>{{item.name}},{{item.size}}</td>
{% if forloop.counter|divisibleby:2 %}
</tr>
<tr>
{% endif %}
{% endfor %}
</tr>
{% endif %}
You forgot to close <td> tag.
<table>
<tr>
{% for item in items %}
<td>
{{item.name}},{{item.size}}
</td> <!-- here -->
{% endfor %}
</tr>
</table>
