User ID specific data

[murad]

Hi,

I am trying to build a simple sales report app , Where the user login and view his related data, I have 2 collections , Users and Test1 which is the sales database.
I have created a column in Test1 which is the user _id from users collection.

Now I have created a local storage parameter so when the user login it saves the user id to the second screen which is the report screen
I have mapped the services as attached but still returning all data.
Do i miss some steps ?

Appreciate your support

Hi Murad,

For your case you just need to click on "where" JS button and add following JS code:

pre

var whereObject = {"UserID": value};

return JSON.stringify(whereObject);

/pre

Also i can suggest you to use Pointer type instead of string to link two collections.

See details here: http://devcenter.appery.io/documentat...

Hi Yurii ,

Thanks you so much it worked perfectly

One quick question , in the pagination how can I make the next button disappear at the end of data records ? I have it now and at the end of the grid it keeps pressing next here is the screenshot

Hi Murad,

You can read more info about pagination here: http://devcenter.appery.io/tutorials/...

There describes how to use "limit" "skip" and "total".

But there is no information about how to get "total". Here is way to get it:

1. Clone "list" service for collection you need.

2. Rename it with name "......count".

3. Open "request" service tab.

4. Add "count" parameter with value "1".
   Details: http://prntscr.com/5ndzqs/direct

5. Navigate to "test" service tab and click "test". And you will see response with all items in your collection.

6. Now you can use this service to populate "total" variable. And use this variable as described in given above tutorial.

Hi Yuri ,

For the total , I used the same query service , Tested and is its returning the correct count see pic.Now I need the VAR to be use
d in the Next button so the next but will disappear after end of report , What is the required code to be amended in the "Next "button event ?

[murad]

please note that I have used the UserID int "where " so the query returns only items related to the user , What i need is to return the total count for each user so the next button disappears automatically at the end of pages.

many thanks for your great support

Hi Yuri ,

Worked well thank you .
now I need to complete the search ,I have built the search screen and want to return search results based on 2 input values combined with the UserID which is stored in the local storage after successful login

I wrote this code in the " where button " but still returning undesired results which is the whole collection search , What should i do with this code ?

return '{"$or":[{"Area":{"$regex":"^'+value+'", "$options":"i"}},{"ItemDescription":{"$regex":"^'+value+'", "$options":"i"}}]}{"$and":[{"UserID ": "' + Apperyio.storage._id.get() + '"}';

Hi Murad,

Glad you get it work.

Also i can suggest you to use whereObject instead of whereString it's very clear to work with. Where string - is so much hard to write correctly.

Also you should use logic operators to combine several conditions.

Here is example for your case:

precode

var whereObject = {
$and: [
{"UserID": Apperyio.storage._id.get()},

Code: Select all

     {$or: [ 
         {"Area": {"$regex": value, "$options": "i"} }, 
         {"ItemDescription": {"$regex": value, "$options": "i"} }, 
     ]} 
 ] 

};
return JSON.stringify(whereObject);

/code/pre

Regards.

Thanks Allot worked again

I know that appery DB don't support offline log-in, If the user logged in and didn't logout just click the ipad home button is it going to keep the session in the multi tasking if the app pressed again ?

Hi Murad,

If you store your sessionToken in localStorage - it will store session if you leave app.. And even after you reboot your phone.
