I have this:
{% for row in data: %}
<td
{{'value={{row['value']}}' if 'showit' in map and header in map['showit'] and 'value' in row}}
> ... </td>
{% endfor %}
But obviously that's not working. Trying to add an HTML attribute to the cell using a secondary column in the row dict. Any thoughts?
Assuming your trouble is with the syntax getting the row['value'], concatenate the strings rather than trying to nest the {{ }}s:
{{ 'value=' + row['value'] if True }}
Replace the True with your condition of course. If you need to quote the param:
{{ 'value="' + row['value'] + '"' if True }}
As #Reza-S4 suggested you can also put the conditional outside the print statement to be a little clearer:
{% if 'showit' in map and header in map['showit'] and 'value' in row: %}
value="{{ row['value'] }}"
{% endif %}

I have a list that looks like this:
[(u'Element1', u'Description1', u'Status1), (u'newElement2', u'newDescription2', u'newStatus2), (u'nextElement3', u'nextDescription3', u'nextStatus3), (u'anotherElement4', u'anotherDescription4', u'anotherStatus4)]
I have an ansible playbook that uses a jinja2 template to render the list to a text file. The template file looks like this:
{% for item in description | batch(3, ' ') %}
{% for el in item %}
{{ el }}
{% endfor %}
{% endfor %}
But this returns the text file to look like this:
[u'Element1', u'Description1', u'Status1]
[u'newElement2', u'newDescription2', u'newStatus2]
[u'nextElement3', u'nextDescription3', u'nextStatus3]
[u'anotherElement4', u'anotherDescription4', u'anotherStatus4]
What I want the report to look like is this:
Element1 Description1 Status1
newElement2 nextDescription2 newStatus2
nextElement3 nextDescription3 nextStatus3
anotherElement4 anotherDescription4 anotherDescription4
Is there a way to remove the unicode characters and render the lists this way?
For example:
{% for row in description %}
{% for cell in row %}
{{ "%-22s"|format(cell) }}
{%- endfor %}
{% endfor %}
Yields:
Element1 Description1 Status1
newElement2 newDescription2 newStatus2
nextElement3 nextDescription3 nextStatus3
anotherElement4 anotherDescription4 anotherStatus4
But to get a dynamic padding - depending on a max length of an element in a column - looks like a much more complex task: {{ "%-22s"|format(cell) }} can be replaced with {{ "{0}".format(cell).ljust(width) }} where width can be a variable, but likely it would require another loop first to collect the lengths.
You could try
{% for el in item %}
{% for e in el %}
{{ e }}
{% endfor %}
{% endfor %}
Or use html tables if you want to be able to change formatting
I am trying to create a (latex) table using jinja2. I defined a macro to help me to create the table:
{% macro table(header, rows, columns) %}
\begin{tabular}{(formatting, later)}
{{ row(header) }}
{% for row in rows %}
{% for column in columns %}
{{ caller(row, column) }} & % *here*
{% endfor %} \\
{% endfor %}
\end{tabular}
{% endmacro %}
I can use the template like this:
{% call(row, column) table.table(header, rows, columns) %}
Content at row = {{row}}, column = {{column}}
{% endcall %}
I quite like how these macros work. The problem is however that I would like to join the results of the macro by a & sign rather than
playing a sign after each row. Essentially now I have this:
Content at row = 0, column = 0 &
Content at row = 0, column = 1 & \\
and I would like to get this instead:
Content at row = 0, column = 0 &
Content at row = 0, column = 1 \\
Is it possible to use filters on macro results? Is there some other way to generate a table where each cell is another jinja2 template depending on parameters?
I'm not familiar with a join functionality in Jinja itself. However it does have built in indexes on your loop. Using loop.last you can determine where to change the output symbol
{% macro table(header, rows, columns, ) %}
\begin{tabular}{(formatting, later)}
{{ row(header) }}
{% for row in rows %}
{% for column in columns %}
{{ caller(row, column) }} {% if loop.last %}\\{% else %}&{%endif%}
{% endfor %}
{% endfor %}
\end{tabular}
{% endmacro %}
Here's documentation on the other loop variables that are available: http://jinja.pocoo.org/docs/2.9/templates/#for
I have MultipleChoiceFieldfield
OPTIONS = (
("AUT", "Austria"),
("DEU", "Germany"),
("NLD", "Neitherlands"),
)
countries = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple(attrs={"name": "select_0","class": "fff"}),
choices=OPTIONS)
I build my own html structure for this field and this is simplified code:
{% for value, text in simple_search_form.countries.field.choices %}
{{value}}
{{text}}
{% endfor %}
How do I get and index of each element here?
I need to have
{{value}}
{text}}
{{index}}
If it's in a for loop, you can use
{{ forloop.counter0 }}
I have strings like the following:
Team Li vs. Team Aguilar || SCORE (W-L-T): 5-4-0
Favors Flavors vs. Cupcakes For Breakfast || SCORE (W-L-T): 11-2-1
I would like the text to be green if the "W" value is greater than the "L" value, and red if the "L" value is greater than the "W" value. I have the following code in Jinja2 that works for the first case, but does not work for the second case. It incorrectly displays the string as red, even though the "W" column is greater than the L column.
{% for item in matchups %}
{% if (item[-5]|int) > (item[-3]|int) %}
<font color='green'>{{ item }}</font>
{% elif (item[-5]|int) == (item[-3]|int) %}
{{ item }}
{% else %}
<font color='red'>{{ item }}</font>
{% endif %}
<br>
{% endfor %}
I understand that my code fails because the second string has 2 digits. Is there a good way to fix this issue?
This is a Jinja2 problem, so answers in Jinja2 would be great. However, a Python solution might also work too.
You can extract the elements with two splits (using variables for clarity):
first to get the last column (split by whitespace) element:
{% set results = item.split()[-1] %}
then to get the first and second of the results (split by the dash):
{% set w = results.split('-')[0]|int %}
{% set l = results.split('-')[1]|int %}
The full code (also with a condition to process only lines containing SCORE to handle the one from your now-edited-out example with *************):
{% for item in matchups %}
{% if 'SCORE' in item %}
{% set results = item.split()[-1] %}
{% set w = results.split('-')[0]|int %}
{% set l = results.split('-')[1]|int %}
{% if w > l %}
<font color='green'>{{ item }}</font>
{% elif w == l %}
{{ item }}
{% else %}
<font color='red'>{{ item }}</font>
{% endif %}
<br>
{% endif %}
{% endfor %}
I used Django framework and MySQL database. I tired to show full names in a row, and it shows me encoded results on the html page like below. I tried to put decode option on python, but it didn't work well. If I use fetchone() command, it shows a correct word. However, it shows me different result if I use fetchall() command. Can you see the errors?
profile.py
cursor = connection.cursor()
cursor.execute("SELECT full_name FROM myapp_profile ORDER BY idx DESC")
results = cursor.fetchall()
x = cursor.description
resultsList = []
for r in results:
i = 0
d = {}
while i < len(x):
d[x[i][0]] = r[i]
i = i+1
resultsList.append(d)
context = Context({'data' : resultsList })
return HttpResponse(loader.get_template('profile/profile_list.html').render(context))
result on html
{'full_name': u'\uae40\uc9c0\uc120'}
{'full_name': u'\uc774\uc8fc\ud604'}
{'full_name': u'\uae40\uae30\uc790'}
{'full_name': u'\uae40\uae30\uc131'}
{'full_name': u'\uae40\uc544\uc601'}
html code was wrong..
it was like this before..
{% if data %}
There are {{ data|length }} records:
{% for e in data %}
<br />
<td> {{ e }} </td>
<br />
{% endfor %}
{% else %}
There are no records in the system
{% endif %}
I changed it like this, and it worked
{% if data %}
There are {{ data|length }} records:
{% for e in data %}
<br />
<td> {{ e.full_name }} </td>
<br />
{% endfor %}
{% else %}
There are no records in the system
{% endif %}
