how to store likes data in flutter - database

I'm developing an app in which I need to show come "coupons" I get from the API. I also have a "liked coupons" page where I need to show the ones the user has liked. I'm facing 2 problems here:
1- I don't know how to store likes, should I implement a local database for everything or should I ask our back-end team to save the liked/not liked state on the server?
2- I have a model class for coupons, and I have a coupon_list widget which is a horizontal listview.builder(). the problem is that some coupons are being showed in 2 or 3 different lists and I need them to all turn to liked when user likes an instance from a single list. how can I do that? (I want to do something like working with pointers in c++, passing the ACTUAL variable instead of it's value so it changes globally)

I would like to suggest you to store it in server as well. (Ask to your back-end team to add parameter) So that if user logout or sign in from different device "liked coupons" data will be available in all cases.
And for 2) multiple coupon entry you have to manage it via unique id. Like every coupon has its unique series no / pattern num. So you can put condition on that. i.e. Add "unique_no" to liked_list from all available list of coupon

Solution
Use Shared Preferences! This is something like a database on the device you are currently running. So if the user makes a like you can save that on their device!
To add Shared Preferences to your app look this video
Hope it helps!

WordPress : make categories automatically match according to external API Value

I'm managing a company website, where we have to display our products. We however do not want to handle the admin edit for this CPT, nor offer the ability to access to the form. But we have to read some product data form the admin edit page. All has to be created or updated via our CRM platform automatically.
For this matter, I already setup a CPT (wprc_pr) and registered 6 custom hierarchical terms: 1 generic for the types (wprc_pr_type) and 5 targeting each types available: wprc_pr_rb, wprc_pr_sp, wprc_pr_pe, wprc_pr_ce and wprc_pr_pr. All those taxonomies are required for filtering purposes (was the old way of working, maybe not the best, opened to suggestions here). We happen to come out with archive pages links looking like site.tld/generic/specific-parent/specific-child/ which is what is desired here.
I have a internal tool, nodeJS based, to batch create products from our CRM. The job is simple: get all products not yet pushed to the website, format a new post, push it to the WP REST API, wait for response, updated CRM data in consequence, and proceed to next product. Handle about 1600 products today on trialn each gone fine
The issue for now is that in order for me to put the correct terms to the new post, I have to compute for each product the generic type and specific type children.
I handled that by creating 6 files, one for each taxonomy. Each file is basically a giant JS object with the id from the CRM as a key, and the term id as a value. My script handles the category assertion like that:
wp_taxonomy = [jsTaxonomyMapper[crm_id1][crm_id2]] // or [] if not found
I have to say it is working pretty well, and that I could stop here. But I will have to take that computing to the wp_after_insert_post hook, in order to reaffect the post to the desired category on updated if something changed on the CRM.
Not quite difficult, but if I happen to add category on the CRM, I'll have to manually edit my mappers to add the new terms, and believe me that's a hassle.
Not waiting for a full solution here, but a way to work the thing. Maybe a way to computed those mappers and store their values in the options table maybe, or have a mapper class, I don't know at all.
Additional information:
Data from the CRM comes as integers (ids corresponding to a label) and the mappers today consist of 6 arrays (nested or not), about 600 total entries.
If you have something for me, or even suggestions to simplify the process, I'll go with it.
Thanks.
EDIT :
Went with another approach, see comment below.

How can the category and product fields in Shopizer be customized, if possible at all?

I am currently using Shopizer as a sort of headless CMS, leveraging its out of the box admin pages and REST API for the content. There is a page for editing products in the admin system but I would like to add and/or remove specific fields. Making changes to the base code seems to be the most obvious solution but it is taking me a significant amount of time to implement it successfully.
Is there some sort of a config file or an initialization process to customize the fields for creating categories and products using Shopizer's admin page? What is the best practice for this scenario if the former approach is not possible?
If you need to add fields the easiest way is to add them in model objects
com.salesmanager.core.model.*
Example of an annotated field
#Column (name ="IP_ADDRESS")
private String ipAddress;
Once you restart your instance the new field will be available.

Is there a clean way of users managing their own locations?

A lot of my site is dynamically generated dependant on the user location.
To get an initial fix I am currently using the Smart_IP module which does this based on the user IP address - which works great as a starting point. I can access $_SESSION['smart_ip']['location']['longitude'] & $_SESSION['smart_ip']['location']['latitude'] as required - perfect!
But I need to allow my user to override this..
Using HTML5 geolocation. I want to only do this on user request, ie click 'locate me', rather than requesting their location uninvited.
Using one of a few pre-defined locations selectable by the user.
Using an inputed address by the user.
Is there any drupal module I can use for this, or how else could I achieve it?
-
Just to clarify, I am talking about anonymous users here - the general public visiting my site. I just want them to be able to refine their 'location' by overriding the defaults I give them using smart_ip.
I suggest to use Geolocation field and all it's submodules or Geofield. Last one provides more input methods.
Use the Address field module to allow the user create multiple addresses into a node (or even into his profile), Geocoder module to get the lon/lat from these addresses and then a Views to display them in a list.
Same as 2 but without views.
If you want to allow user select one of the 3 methods you can use an other - helper - field (eg a select list with the 3 options).
Finally you should add an extra field to store the lat/lon pair final values maybe with Computed field module or 2 simple textfields that will get the selected values through javascript.

Show Opportunity related Contacts in Custom Object Field

I have the next issue.
I have a custom object called 'Application', and I have this requirement:
"Show all Contacts related to an Application. Create a field on Application object, must be read only".
I solve it with apex code. 'Application' has a lookup to Opportunity, Opportunity to Account, and all my contacts have AccountId, so this way, I get all the contacts using apex code in a trigger.
But, I've been ask to change this to a Formula field in Application object.
So, my issue is next. I'm not able to get all contacts with advance formula editor, because they're not part of any object. I have no master-detail relationship.
Does any one know how can I achieve this using configuration? I should not use apex code for this req.
Thank in advance guys.
I don't think you can do it.
In formulas / merge fields syntax there's no way to go "up, up then down" (Application -> Opportunity -> Account -> down to Contacts related list). There's also nothing that would let you loop through Contacts (and display what? Ids? Names? Emails?). Roughly speaking you can only go up through dots.
You might want to explore path of "cross object workflow" rules but I imagine that when I add a new Contact to Account it should somehow "spread itself" to all related Applications? There's no straight way to fire a workflow on delete too - so you'd eventually end up with inaccurate list.
I'd say trigger was a good solution. Maybe it ws unoptimized but if it has to be in a field - tough.
There might be a fairly simple way of achieving that by embedding a visualforce page within Application page layout.
This should be doable with pure Visualforce (so technically there will be no Apex code ;))
Something as simple as
<apex:relatedList list="Contacts" subject="Application__c.Opportunity__r.AccountId" />
would be a good start (if you want your own layout and not a rel. list - you should be still able to pull it off with <apex:repeat> or <apex:pageBlockTable>.
There's one BUT here: it's not a field, just a display trick. Forget about using it in reports, mobile applications etc.
Another way - would it be acceptable to be 1 click away from these contacts? You could make a report "Account with Contacts", filter it by Id of one Account and later use "URL hacking" to change the filter depending on from which Application you'll click it. This link could be either a formula field or a real custom button/link. Technically - it's pure config, no apex & VF.
You can read more about URL hacking at Ray Dehler's excellent post and specifically about dynamic Reports here or here.

Is this the right db design for the most flexible and modular CMS with user management in CakePHP?

I would like to ask you guys if you could review my database design. I think it is quite self-explanatory, but to be absolutely clear:
My goal is to make an application which has a super flexible user management (which is why the groups are in tree-form and the groups and users have a habtm relationship) and a super modular way to build pages (which is why the pages consist of widget-blocks).
The reason I made users and profiles separate is because the users table will not change and is only needed for authentication and authorization. However, the profiles table will change according to the wishes of the client. So it might not have a signature, but an avatar field instead. Or maybe it will be completely empty / not exist at all.
A widget could be anything, it could be a poll, it could be a piece of content, it could be a navigation, it could be a collection of comments, whatever.
The reason I chose to make subdomains, locales and layouts separate tables instead of just putting the names into pages is because I want to limit the options that are available to the client. Just because I have a three-columns.ctp in my layouts folder doesn't necessarily mean I want the client to be able to choose it.
Same goes for the widgets. And besides limiting choice, not every plugin, controller and action in my plugins-folder is a widget, so I need a table to clarify which are.
A block is a widget on a page which sits in a container (e.g. the right column in a 3 column layout) at a particular position which is decided by the index (lower index means higher).
So that's my explanation, what do you guys think? Is this as good as it can be? Or do you have (a) suggestion(s) to make it even more flexible and modular.
[edit] Oh and to be clear, the widgets will of course have their own tables to store the information they need to store.
Well, I think that everything is great except "profiles".
When you try to get data from a logged user:
$this->Auth->user();
I don't think that you will get data about "profiles" so you will have to find profile by $this->Auth->user('id') etc. I think that you should merge "profiles" and "users" tables into "users" table.
So when you want to save, let's say, "signature" you should just put it in $this->request->data; and call $this->User->save($this->request->data); and the signature will be updated.
EDIT:
You can leave it the way it is but, to get other data than user, you will have to put:
$id = $this->Auth->user('id');
$current_user = $this->User->findById($id);
