Odoo is the world's easiest all-in-one management software.
It includes hundreds of business apps:
Here is the template code where it doesn't work as expected. I expected [10, 10, 10] for foo array but insted it shows [0, 1, 2] when I display the output.
< t t-set = "foo" t-value = "[]" />< t t-foreach = "[1,2,3]" t-as = "i" >
< t t-set = "foo" t-value = "foo + [10]" />
< p > < t t-esc = "i" /> </ p >
</ t >
the below piece of code also throws an error of No append function.
< t t-set = "foo" t-value = "[]" />
< t t-set = "foo" t-value = "foo.append(10)"/>
In Odoo templates, the t-set attribute is used to set a variable to a given value. However, t-set doesn't support modifying a list in-place, such as appending elements to it.
To accomplish this, you can use the t-operation attribute instead, which allows you to perform operations on the value of a variable. In your case, you can use the t-operation attribute to append elements to the foo list as follows:
t-set="foo" t-value="[]"/> t-foreach="[1,2,3]" t-as="i"> t-operation="foo.append(10)"/>t-esc="i"/>
Alternatively, you can use the t-call attribute to call a Python function that modifies the list in-place. Here is an example:
!-- Define a Python function that appends 10 to the given list --> t-call="website.append_to_list" t-args="foo"/> t-foreach="[1,2,3]" t-as="i"> t-call="website.append_to_list" t-args="foo"/>t-esc="i"/>
foo = t-esc="foo"/>
In the Python code of your website, you would need to define the append_to_list function as follows:
def append_to_list(foo): foo.append(10)
Hope this helps!
Hi,
Please try like as follows:-
<t t-set="foo" t-value="[]"/>
<t t-foreach="[1,2,3]" t-as="i">
<t t-set="foo" t-value="foo + [10]"/>
</t>
<p>
<t t-esc="foo"/>
</p>
