Eloquent using wrong key for some tables - laravel

Question

Using: Laravel 5.5
I Constructing addresses using some address elements (like: district, area, zip etc) as dropdowns & also some user inputs.
I have 5 address element & one of their schema is:
Schema::create('address_districts', function (Blueprint $table) {
$table->increments('id');
$table->integer('admin_id')->unsigned();
$table->string('name');
$table->timestamps();
$table->foreign('admin_id')->references('id')->on('admins');
});
This is for Districts, & I have another 3 exactly same like this called, address_thanas, address_areas, address_building_names & address_zips;
The only exception for the last one is that has code instead of name on other tables:
Schema::create('address_zips', function (Blueprint $table) {
$table->increments('id');
$table->integer('admin_id')->unsigned();
$table->string('code'); // Look other table has name here........
$table->timestamps();
$table->foreign('admin_id')->references('id')->on('admins');
});
I store constructed addresses on the table called addresses
Schema::create('addresses', function (Blueprint $table) {
$table->increments('id');
$table->integer('district_id')->unsigned();
$table->integer('thana_id')->unsigned();
$table->integer('area_id')->unsigned();
$table->integer('zip_id')->unsigned();
$table->integer('building_name_id')->nullable()->unsigned();
$table->string('building');
$table->integer('floor');
$table->string('apt')->nullable();
$table->text('comment')->nullable();
$table->timestamps();
$table->foreign('district_id')->references('id')->on('address_districts');
$table->foreign('thana_id')->references('id')->on('address_thanas');
$table->foreign('area_id')->references('id')->on('address_areas');
$table->foreign('zip_id')->references('id')->on('address_zips');
$table->foreign('building_name_id')->references('id')->on('address_building_names');
});
In Address Model I've defined relationships like:
public function district() {
return $this->belongsTo(AddressDistrict::class, 'district_id');
}
public function thana() {
return $this->belongsTo(AddressThana::class, 'thana_id');
}
public function area() {
return $this->belongsTo(AddressArea::class, 'area_id');
}
public function building_name() {
return $this->belongsTo(AddressBuildingName::class, 'building_name_id');
}
public function zip() {
return $this->belongsTo(AddressZip::class, 'zip_id', 'id');
}
Then when I try to create a new address using Address::create($data)
I get error:
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'name' in 'where clause' (SQL: select count(*) as aggregate from `address_zips` where `name` = 2)
Here we can see that it is comparing the key name instead of id
I noticed that this is not reporting that the data cannot be inserted or something like that, it fails to count related model & for that aborts insertion of data
Why is that?
But the strange thing is I can retrieve data by (inserted a row manually into db for testing to see if that can retrieve data)
$addresses = Address::orderByDesc('created_at')->get();
//loop as $address
$address->district->name
$address->zip->code
...
& this works perfect
When I am creating a new record I need that query look like:
select count(*) as aggregate from `address_zips` where `id` = 2
Any help will be highly appreciated.
Thanks for reading this long question.

The problem is in your $data array. Probably you copied a form with an input name, you need to rename it to code in order to save the values automatically.
Alternatively, you can set the input manually
$address = new Address();
$address->code = request('name');
$address->save();
