* Returns true, if the thing requested (identified by `name`) is allowed for each
|
|
* provided data in `dataList` by the user given by `user_id`.
|
|
*
|
|
* Convention: For each action and presenter, there will be an permission check.
|
|
* This is not enforced but a good guideline to see which permission check belongs
|
|
* to which usecase.
|
|
*
|
|
* Returns an object with the allowed giving the result. If `allowed` is true, additional
|
|
* permission related information can be provided in `addition`. There is either `null` or
|
|
* an object per data. E.g. for motion update the supporters my be cleared, if the user has
|
|
* no manage perms. This will be given as `{clearSupporters: true}`.
|
|
*
|
|
* If it was not allowed, one of the data in `dataList` was not allowed. This index is given
|
|
* together with the `reason` in `error_index`.

* - Motion submitter:
