Add hidden and private surveys with access right checking

[hguenot]

• Hidden survey : So the survey is not visible while user is creating it
• Private survey : Choose users who can answer to survey
• Access right : user can't see hidden or private survey
• Make fields disabled when survey is answered
• Search user is accessible only if IdentityClass implements SurveyInterface

Hi!

What we do with the already user assignment existed feature (respondents.php)?

[hguenot]

Hi,

On my understanding, anyone can vote on a survey. And in respondents.php, we can see who has voted and reset the vote status. When I click on the red trash, "respondent" disappear, and user can click on "done" again. Furthermore, there is no restriction anywhere in the code (I add it in this pull request).

My "private" flags is a restriction of who can vote... Maybe we can merge the two things in one... but I think the "respondent" view will be difficult to understand...

Sounds reasonable. But what if will be added many users (fa 1000). Without pagination, it will slow down the page...

[hguenot]

Maybe we raise memory limit before :D Yes of course... I didn't make test load... I think if you need to add 1000 users, we need to think another way to restrict the poll (ie restrict to user with a specific access right or allows developer to "inject" their own users filtering class/method)

[hguenot]

But I will update to use same method as respondents.

In my case, I do so: In the users GRID, a have checkboxes which can bulk assign the survey through modal

And only these users can access to the survey.
