QUESTION
I am using Quasar, and I would like the drawer
changes into mini
mode automatically whenever the browser gets smaller by users. For now, it's always opened even I narrows the browser.
It's what I tried below:
...ANSWER
Answered 2021-Jun-11 at 13:21In your code you have made several mistakes;
You are repeating your data property
miniState
as a computed property. TheminiState
property inside the data function will override the computed property; thus it will always befalse
You are not returning a value from your computed property; instead you are only assigning.
Still; window properties such as
innerWidth
is not reactive and watchable in Vue. Please correct me if I am wrong. Thus, watchingwindow.innerWidth
will not trigger every time the window is resized.
Since you are using Quasar, you can make use of the the screen
plugin which comes with Quasar. You dont have to install anything, the screen
plugin is installed by default. Here is the link to the docs.
I have put below a very minimal example of the code with the functionality you required. This is not the code you have put in your post above. I extracted the drawer and the content from the Quasar documentation here
Now the drawer will automatically go into mini
mode when the screen size is below 500 px
; this is of course configurable.
Also; on a side note, if you are only starting with Vue and Quasar, Vue is now upgraded to Vue3
which comes with the composition api. Quasar is also being upgraded to version 2 which supports Vue3
.
Follow the comments below and you will understand the code!
QUESTION
is it possible to have a highlight colour for the selected item of an Expansion Item ?
...ANSWER
Answered 2021-Jun-05 at 22:39Yes, you can.
Since quasar provides styled wrappers over HTML DOM elements, custom CSS can be applied to the class which can be found out by inspecting in chrome dev tools.
In your case, the class name is: .q-expansion-item--expanded
Add this to component CSS:

I'm having issues running a Django (2.2) migration that contains a somewhat complex CheckConstraint
, running over python 3.6.9.
The underlying database is PostGIS 9.5.
The Model:

Answered 2021-Mar-14 at 12:08It turned out the issue was the constraint name
As pointed out by a colleague:
Something I've found
'%(app_label)s'
and'%(class)s'
were added on Django 3.0, and we are on Django 2.2!
Once I got rid of those, the migration ran correctly.
QUESTION
I have a hierarchical list component where child items have checkboxes. Checkbox actions(check/uncheck) must keep the parent component in sync with the checkbox's changed state. I cannot figure out how to achieve this using v-bind.sync recursively. My code is as below:
Menu.vueThis component holds the hierarchical list. (Only relevant code included)
- HierarchicalCheckboxList is the component that displays the hierarchical list
- Property 'value' holds the check/uncheck value (true/false)
- Property 'children' contains the child list items
...How do I define the .sync attribute on HierarchicalCheckboxList and with what parameter?
ANSWER
Answered 2020-Dec-01 at 05:02Figured out how to do it after I broke the code down from the whole 2000 line code to a separate 'trial-n-error' code of 20 lines and then things became simple and clear.
Menu.vueA few changes in the parent component in the HierarchicalCheckboxList declaration: Note the sync property

I have a q-list
with several q-expansion-item
s as children. The q-expansion-item
s are assigned to a list, so there is only one open at any given time.
ANSWER
Answered 2020-Sep-30 at 12:54You can achieve this without using id's and events. You can use v-model
instead.

QUESTION
I'm using a store in Quasar (based on VueJS), and when I insert a new object in my database, the store updates. The objects are named "demande" and they have a "dateDemande" property. Everything looks fine but for some reason, this property doesn't show when I want to display it in a caption, although it displays in the q-card section:
...ANSWER
Answered 2020-Feb-07 at 12:24maybe the problem is that caption
prop required string and you pass a date property to it.
try to call .toString()
on it
for example in your code

I'm now trying to make multiple-item filtering in Quasar, Vue's framework.
I'm currently using input and checkbox. There seems to be no problem, but the select item disappears.
