Ext JS 6.2.0本地化覆盖失效问题咨询

Hey Andy, let's tackle your two main issues here—the override warning and the missing localized grid column headers.

1. Resolving the "Overriding existing mapping" Warning #

That warning is telling you your main app's clt.view.users.UsersModel is overriding the locale version (clt.locale.en.view.users.UsersModel) instead of the other way around. This happens when your locale classes load after your core app code, reversing the intended override flow.

Here's how to fix it:

• Double-check your app.json to ensure your locale package is configured correctly and loads before core app code. For example:

  "locale": {
      "enabled": true,
      "default": "en",
      "packages": [
          {
              "name": "clt-locale-en",
              "path": "locale/en"
          }
      ]
  }
  

• Use explicit overrides in your locale ViewModel to target the core class directly. This removes ambiguity and fixes the mapping conflict:

  Ext.define('clt.locale.en.view.users.UsersModel', {
      override: 'clt.view.users.UsersModel',
      // Localized data goes here
      data: {
          columnNames: {
              username: 'Username',
              email: 'Email Address'
              // Add other localized column labels
          }
      }
  });
  

2. Fixing Missing Localized Grid Column Headers #

If your column headers still don't show up after resolving the warning, check these common issues:

• Verify ViewModel bindings: Ensure your grid columns are correctly bound to the localized data in the ViewModel. In your clt.view.users.Users view, it should look like this:

  Ext.define('clt.view.users.Users', {
      extend: 'Ext.grid.Panel',
      viewModel: 'users',
      columns: [
          { text: '{columnNames.username}', dataIndex: 'username' },
          { text: '{columnNames.email}', dataIndex: 'email' }
          // Match paths to your locale ViewModel's data structure
      ]
  });
  

• Confirm locale file loading: Use your browser's Network tab to check if clt.locale.en.view.users.UsersModel.js loads successfully. Fix any 404 errors by adjusting the file path in your package config.
• Check for typos: It's easy to misspell class aliases, binding paths, or localized keys. Double-check that:
  • The ViewModel alias (viewmodel.users) matches in both core and locale files.
  • The keys in your locale ViewModel's data object exactly match what's referenced in the grid columns.
• Test with hardcoded values: Temporarily replace the binding with a hardcoded string (e.g., text: 'Username'). If that shows up, the issue is with your ViewModel override or binding; if not, debug your grid configuration.
