I want to set the variable key before using it
"columns": [
{% for key, value in columns %}
{"data": "{{ key }}"},
{% endfor %}
{ "data": "id" }
]
My approach:
"columns": [
{% for key, value in columns %}
{% set result = '{{ key }}' %}
{"data": "{{ result }}"},
{% endfor %}
{ "data": "id" }
]
But it is not working. I get the error message:
Requested unknown parameter '{{ key }}'
{% set result = key %}
From what I see, you want to set the value of result variable, result of key is already set, you just didn't access it correctly.

I've an User entity and EasyAdmin (EA) UserCrudController for manage to them.
The User entity has active boolean field. And I want that field will be disabled for current user in admin interface.
I got a working solution:
{% extends '#EasyAdmin/crud/index.html.twig' %}
{% block table_body %}
...
{% for field in entity.fields %}
{# disable active field for current uset #}
{% if is_granted('IS_AUTHENTICATED_FULLY') %}
{% if app.user.id == entity.instance.id and field.property == 'active' %}
{% set templatePath = 'admin/crud/field/_boolean_disabled.html.twig' %}
{% else %}
{% set templatePath = field.templatePath %}
{% endif %}
{% endif %}
<td data-label="{{ field.label|e('html_attr') }}" class="{{ field.property == sort_field_name ? 'sorted' }} text-{{ field.textAlign }} {{ field.cssClass }}" dir="{{ ea.i18n.textDirection }}">
{{ include(templatePath, { field: field, entity: entity }, with_context = false) }}
</td>
{% endfor %}
...
with override EA boolean template.
But I wouldn't want to override EA boolean template and only complete field.formTypeOptions by element 'disabled': 'true'
{% for field in entity.fields %}
{# disable active field for current uset #}
{% if is_granted('IS_AUTHENTICATED_FULLY') %}
{% if app.user.id == entity.instance.id and field.property == 'active' %}
{% set field.formTypeOptions = field.formTypeOptions|merge({'disabled': 'true'}) %}
{% endif %}
{% endif %}
<td data-label="{{ field.label|e('html_attr') }}" class="{{ field.property == sort_field_name ? 'sorted' }} text-{{ field.textAlign }} {{ field.cssClass }}" dir="{{ ea.i18n.textDirection }}">
{{ include(field.templatePath, { field: field, entity: entity }, with_context = false) }}
</td>
{% endfor %}
But for this path I get an error: "Uncaught PHP Exception Twig\Error\SyntaxError: "Unexpected token "punctuation" of value "." ("end of statement block" expected)." at /home/vagrant/code/blog.local/templates/admin/crud/user/index.html.twig line 27"
line 27: {% set field.formTypeOptions = field.formTypeOptions|merge({'disabled': 'true'}) %}
When I do:
{% set x = field.formTypeOptions|merge({'disabled': 'true'}) %}
{{ dump(x) }}
array:7 [▼
"required" => false
"row_attr" => array:1 [▶]
"attr" => array:1 [▶]
"label" => "Active"
"label_translation_parameters" => []
"label_attr" => array:1 [▶]
"disabled" => "true"
]
I get the required array, but I get the same error when I try to assign a new value
{% set field.formTypeOptions = field.formTypeOptions|merge({'disabled': 'true'}) %}
What am I doing wrong? Thanks
I think its because the merge function does not like punctuations. Try to set the value to a variable before:
Change:
{% set field.formTypeOptions = field.formTypeOptions|merge({'disabled': 'true'}) %}
To:
{% set options = field.formTypeOptions %}
{% set field.formTypeOptions = options|merge({'disabled': 'true'}) %}
You could already do that in UserCrudController and avoid that logic in Twig:
public function configureFields(string $pageName): iterable
{
// ...
// check user/roles
$isInputDisabled = true;
if($this->isGranted('ROLE_ADMIN')){
$isInputDisabled = false;
}
// ...
$active = BooleanField::new('active', 'Active')
->setFormTypeOption('disabled', $isInputDisabled);
// ...
}
I am getting data from a json file into my datatable.
"columns": [
{% for key, value in columns %}
{
"data": "{{ key }}"},
{% endfor %}
]
Like this I get the following output:
id name slug icon
2 Mitarbeiter members [object Object]
3 Angebote offers [object Object]
4 Produkte products [object Object]
5 Felder fields [object Object]
To recieve the data of the object, I changed my code to this:
"columns": [
{% for key, value in columns %}
{ "data": "{{ key }}.name",
"defaultContent": "{{ key }}"},
{% endfor %}
]
This is working well for the object, but now my other fields do not show the value anymore, the show the label of the column:
id name slug icon
id name slug icon
id name slug anchor
id name slug adjust
id name slug cloud
dump of columns:
array:5 [▼
"id" => ReflectionProperty {#6092 ▶}
"name" => ReflectionProperty {#6094 ▶}
"slug" => ReflectionProperty {#6096 ▶}
"icon" => ReflectionProperty {#6097 ▶}
]
Another approach is this:
"columns": [
{% for key, value in columns %}
{% if key is iterable %}
{"data": "{{ key }}"},
{% else %}
{"data": "{{ key }}.name"},
{% endif %}
{% endfor %}
]
But here I get only the output of the icons row...
The json file is this:
[{"id":2,"name":"Mitarbeiter","icon":{"id":2,"name":"anchor"},"slug":"members"},{"id":3,"name":"Angebote","icon":{"id":1,"name":"adjust"},"slug":"offers"},{"id":4,"name":"Produkte","icon":{"id":1,"name":"adjust"},"slug":"products"},{"id":5,"name":"Felder","icon":{"id":1,"name":"cloud"},"slug":"fields"}]
Finally found a solution:
"columnDefs": [
{
"render": function (data, type, row) {
var type = typeof data;
if(type == "object"){
return data.name;
} else {
return data;
}
},
"targets": "_all"
}
],
"columns": [
{% for key, value in columns %}
{ "data": "{{ key }}"},
{% endfor %}
]
Truy to use: of_type('object')
"columns": [
{% for key, value in columns %}
{
"data": "{% if key is of_type('object') %}{{ key }}.name{% else %}{{ key }}{% endif %}"},
{% endfor %}
{ "data": "id" }
]
I have the following example of YAML data structure: (data and structure are subject to change)
settings:
subset1:
sub1: val1
sub2: val2
sub3: val3
subset2: val1
I want to use Jinja to print it as such: (ordering is not important)
subset1.sub2 = val2
subset1.sub3 = val3
subset1.sub1 = val1
subset2 = val1
This is what I have:
{% for key, value in settings.items() recursive %}
{{ key }}{% if value is mapping %}.{{ loop(value.items()) }}{% else %} = {{ value }}
{% endif %}
{% endfor %}
But it gives me this:
subset1.sub2 = val2
sub3 = val3
sub1 = val1
subset2 = val1
Only the first sub element is printed with its respected parent. How can I print all the sub elements with their respected parents properly?
(Again, ordering is not important)
Thanks!
This is how I solved my use case:
from jinja2 import Template
settings = {
'k1': {
'k1': '1.1',
'k2': {
'k1': '1.2.1',
'k2': {
'k1': '1.2.2.1'
},
'k3': {
'k1': {
'k1': '1.2.3.1.1'
},
},
},
},
'k2': {
'k1': '2.1'
},
'k3': '3'
}
template = """
{%- macro treedot(dict,string) %}
{%- for key, value in dict.items() -%}
{%- if value is mapping -%}
{%- if string -%}
{%- set str = string ~ '.' ~ key -%}
{%- else -%}
{%- set str = key -%}
{%- endif -%}
{{ treedot(value,str) }}
{%- else -%}
{%- if string %}
{{ string ~ '.' ~ key }} = {{ value }}
{%- else %}
{{ key }} = {{ value }}
{%- endif -%}
{%- endif -%}
{%- endfor -%}
{%- endmacro -%}
{{ treedot(settings,none) }}
"""
tpl = Template(template)
print tpl.render(settings=settings)
The result will be :
k3 = 3
k2.k1 = 2.1
k1.k2.k3.k1.k1 = 1.2.3.1.1
k1.k2.k2.k1 = 1.2.2.1
k1.k2.k1 = 1.2.1
k1.k1 = 1.1
Better than using the keyword "recursive", using a macro allow recursivity too and allow to pass as an argument the path to the value.
Before this I tried with "recursive" keyword too but wasn't able to achieve my needs since variables inside a loop are reset at each iteration.
i have a problem with twig syntax and merge function ... I have multiple object with 2 field category and price.
I need to create an array or hash (i guess hash is easier but ... i try both) with sum of prices for each category.
So i try many code, and my last is :
{% set test = [ {'category': 'description', 'price': '1'}, { 'category': 'abc', 'price': '2'}, { 'category':'description', 'price': '3'} ] %}
{% set listCategory={} %}
{% for line in test %}
{% set new_category = { 'category': line.category, 'price': line.price } %}
{% if loop.first %}
{% set listCategory = listCategory|merge([new_category]) %}
{% else %}
{% set flag = false %}
{% for category in listCategory %}
{% if line['category'] == new_category['category'] %}
{% set tmp = line['price'] + new_category['price'] %}
{# i try it too#}
{% set category = category|merge([tmp]) %}
{# or i try this#}
{% set category = category|merge({ (category.price) : category.price + new_category.price }) %}
{{ dump(listCategory) }}
{% endif %}
{% endfor %}
{% endif %}
{% endfor %}
I try it since 3 hours and i don't know where i make an error.
When i check my array, i test if the key 'name' exist
if yes, i want to add the price of element to the hash price
if no, i want to add a new array in hash with key = 'name'
Anyone have an idea ? thx for your reading.
I think you are looking for something similar to:
{% set test = [ {'category': 'description', 'price': 1}, { 'category': 'abc', 'price': 2}, { 'category':'description', 'price': 3} ] %}
{% set listCategory={} %}
{% for line in test %}
{% set key = line.category %}
{% if listCategory[key] is defined %}
{# notice here that the key is in brackets () because otherwise it will be interpreted as the string "key" %}
{% set listCategory = listCategory|merge({(key):listCategory[line.category]+line.price}) %}
{% else %}
{% set listCategory = listCategory|merge({(key):line.price}) %}
{% endif %}
{{ key }}: {{ listCategory[key] }}
{% endfor %}
I'm trying to create a json object on twig, so I need to set a variable inside a loop.
After many attempts I found this way, but it's fine when I only have two records, if I have any more you generate the problem:
{% set data = [] %}
{% for artist in artists %}
{% if loop.first %}
{%
set data = {
id : artist.id,
text : artist.name|capitalize() ~' '~ artist.surname|capitalize()
}
%}
{% else %}
{%
set data = [data,{
id : artist.id,
text : artist.name|capitalize() ~' '~ artist.surname|capitalize()
}]
%}
{% endif %}
{% endfor %}
{% set data = {results: data} %}
{{ data|json_encode|raw }}
What I want to achieve is:
{results: [{id: 1, text: "bla"},{id: 2, text: "blabla"},{id: 3, text: "blablabla"}]}
Instead I get:
{results:[[{id:1,text:"bla"},{id:2,text:"blabla"}],{id:3,text:"blablabla"}]}
Is there a way to build a json object inside twig without going crazy?
I've already tried this way .. but rewrites the object and saves in the variable only the last element:
{% set data = [] %}
{% for artist in artists %}
{%
set data = {
id : artist.id,
text : artist.name|capitalize() ~' '~ artist.surname|capitalize()
}
%}
{% endfor %}
{% set data = {results: data} %}
{{ data|json_encode|raw }}
Use merge.
{% set data = [] %}
{% for artist in artists %}
{%
set data = data|merge ([{
id : artist.id,
text : artist.name|capitalize() ~' '~ artist.surname|capitalize()
}])
%}
{% endfor %}
{% set data = {results: data} %}
{{ data|json_encode|raw }}
