I have a List<String> which saves names of categories using shared preferences.
I did everything right but the problem is that every user should have his own categories that he created, if he didn't create anything.. just show default categories not other users categories.
Default categories :
List<String> defaultCategories = [ "Health", "Finance", "Tech"];
Let's say now User A logged in and what he will see is the default categories, he can add to them remove them and that's just fine.. Let's say he added one new category, so he will see it and will be saved in shared preferences and that's good.
User A signs out and then sign in and everything is as he left.. that's great!
Now, when a User B login.. guess what he sees? User A categories!! that's the problem.
I want User B to see default categories if he didn't change anything or sees his own categories.
Can anyone help me in that?
Thanks in advance.
You can manage it multiple ways, and all of them correct so you must just choose one of them.
Ex you can do with these steps;
1.You can cache the default list with a general key in shared preferences.
2.You can add a category list for your user model(nullable),
3.You can save the your user model to your shared preferences with the users unique id.
In this way you can retrive your users category list from shared preferences.
In this way you can retrive default category list from shared preferences.
How can you determine to your user category list?
You can just call the below getter in your view model, controller or where are you needing.
bool get hasUserCategories=>usermodel.categories!= null && usermodel.categories!.isNotEmpty;

I am trying to determine if a specified field role in my user's collection is the one being used within the app. I have simulated this rule like below image in the rules section:
I am trying to access the Admin field of the user collection in this image and check in the rules to allow creating a new product if the user is admin or superuser(can create admin users). Image below:
The rule simulation seems to fail, is there a proper way to access this field in security rules(see both images) or to set up the database properly? The fields were set in a form using radio buttons?
Overall desired task is to allow only certain sections of the app database to be accessed and/or manipulated by my users and also within the app itself, is there a way to query these fields and render the UI and interactions conditionally, to avoid the whole security rules thing?
The superuser is in the owner's collection, omitted for brevity and only one document in it.
Thanks.
Your rule is checking documents in your "projects" collection, but your screenshot is showing contents of doucments in the "users" collection. So, there is obviously a mismatch here.
If you want to allow access to a document using the contents of another document, you will need to get() the other document, then check it for the data you're looking for. An example of this is provided in the documentation. What you will need to do is get() the user document for the currently authenticated user, then check that document's role field. It will look something more like this:
get(/databases/$(database)/documents/users/$(request.auth.uid)).data.role
I would like to check if the current BE user has access to a specific field, e.g. pages.canonical_link or tt_content.header_link.
I can see how this can be done by checking for the permissions of current user to edit the page or content by using e.g. $GLOBALS['BE_USER']->getPagePermsClause(Permission::CONTENT_EDIT). Also it can be checked if user has write access to table by accessing via $GLOBALS['BE_USER']->groupData['tables_modify'] or to the field by checking if the field is an exclude field and checking groupData['non_exclude_fields'].
But groupData is public but internal (so this generates warnings) and I am wondering if maybe I am missing some more general public API to do this. Also, I am not sure if I am missing some things: There are a lot of ways you can configure the access, such as editlock for the page, you can restrict access to edit fields for specific language, etc. etc.
I want to upload course using upload courses menu.
and i want to import the id with the other fields.
I tried "id","shortname","fullname","category" as a filed on the csv.But it uses incremented id instead.
Oh and i want the same thing for user too.
That cannot be done - all ids in Moodle are automatically generated, in order to make sure they always uniquely identify the item (course, user, etc).
Instead of trying to identify the course by id, you should look at identifying it by shortname or idnumber.
how to set read only properties to the particular info path form control based on user logged in?
Your best option (assuming you are using managed code) is to get the user name with either Application.User.UserName or HttpContext.Current.User.Identity and then call IsInRole (I believe it is a member of the WindowsPrincipal class).
Save the result into the value of a field and you can then use the standard conditional formatting to lock the fields you don't want the users changing. I also usually conditionally change the look of those readonly fields (grey background fill etc) so the users don't get confused and think they can edit.
When I go to /_layouts/groups.aspx in my site collection, I only see the first 100 groups. There is no pagination control visible. How do I correct this, to work with more than just the first 100 groups?
You can also modify this view through the standard UI, rather than using code if you need to:
Browse to "http://<site collection url>/_catalogs/users/AllGroups.aspx"
Site Actions-> Edit Page
Modify the List View web part
Under Selected View click the "Edit the current view" link.
You can now edit the view settings like any other in SharePoint.
That list is a sharepoint internal list which cannot be accessed through the API and must be hit by utilizing the object model.
Assuming you're familiar with the SharePoint API,
You need to access your site programmatically
then access the users and groups list, then access the default view on it, and set it's paging property to true.
static void Main(string[] args)
{
//Access the site
using (SPSite _site = new SPSite("http://myurlwithport:800"))
{
//Substitute the appropriate web if it is not the root
using (SPWeb _web = _site.RootWeb)
{
// This is always the name of the users list
SPList userList = _web.Lists["User Information List"];
//This is the view that is causing you trouble
SPView allGroupsView = userList.Views["All Groups"];
//Set this value to true if it is false.
Console.WriteLine(allGroupsView.Paged);
//Set this value to whatever you want if you don't want paging
Console.WriteLine(allGroupsView.RowLimit);
Console.ReadLine();
}
}
}
Hope this does it for ye.
EDIT
Based on OP comments
There is a RowLimit property that you can change instead if you want.
I've added it into the code provided.
I want to share some additional clarification to Michael M's suggestion on updating the "AllGroups.aspx".
Initially, I used a regular Site Collection admin account to access the
"http:///_catalogs/users/AllGroups.asp" page and got access denied.
I then used another Site Collection admin account who's also in the Windows admin group for the SP server and still got access denied.
Finally, I used the SharePoint 2010 Farm admin account that we used to setup the Web App/App Pool, and that finally gave me access to the page.
