About Localization
Localization is the process whereby a user interacts with platform using their preferred language and data formats.
The AgileApps Cloud platform Locale Settings provide a choice of data formats:
- My Settings > Locale Information - Formats chosen by the user for dates, times, and numbers, plus language.
- User Settings - Formats set for the user by the admin.
- Company Information Settings - Default user formats, and the Currency format, which can be changed only by an admin.
- Considerations
-
- If a user's permissions don't allow them to change their personal settings, then the default settings chosen by the company are effectively fixed.
Working with Localized Values
The format you'll be working with depends on the type of data, and the context in which the data is used.
The following table summarizes the situations. Details are in the sections that follow.
Dates and Times Numbers and Currency GUI Search
Filter Criteria
Web Forms
Record IdentifiersUser Format Database Format all other User Format Import Import Format Database Format Export User Format Database Format Formulas and Rules User Format Database Format Java API User Format Database Format JavaScript User Format REST API Database Format Velocity Templates User Format
Interface Interactions
When working with the platform GUI, data is typically displayed and entered in User Format, as determined by the user's Locale Settings. In particular, those settings are used for:
- Dates and times
- Numeric data (currencies, numbers, numbers with decimals, and percentage values)
- Formula Fields that return numeric data
- Rollup Summary Fields that accumulate numeric data
There are exceptions, however:
- When specifying numeric values that will be used in a direct comparison against database data.
In those cases, the Database Format must be used:
- Entering Search data
- Specifying Filter Criteria for a View
- When specifying numeric values that will be used in a direct comparison against database data.
- Numeric data entered in Web Forms must also be in Database Format.
- Numeric data that is displayed as part of a Record Identifier appears in Database Format.
Rules and Formulas
In Rules, and when uing the Formula Builder to specify default field values and computed fields:
- Date and Time values must be specified in User Format
- Numeric values must be specified in Database Format
Imports and Exports
These formats are used for imports:
- Numeric values are in Database Format
- Date and Time values are in a fixed Import Format: YYYY-MM-DD [HH:mm:ss]
As an option, when imported numeric data is in the user's localized format:
- A Pre-Import Rule can be used to convert the incoming numeric values to Database Format.
- To do that, The Java Localization Functions are used. A method must be defined to invoke them in a Java Class, The method can then be invoked by a Rule action to convert the numeric data.
- Or you can save yourself the effort by ensuring that incoming numeric data is in Database Format to start with.)
For exports:
- Numeric values are in Database Format
- Date and Time values are in User Format
Java Programming
Most Java programming entails dealing with the database, which means that data provided in the APIs and returned from them are in Database Format -- except for dates and times, which are in User Format, unless the Field Type is as entered, rather than auto-convert.
However, in a JSP Page, data entered by a user will generally be localized, as will the data displayed to the user. To convert between those user format and the database format, use the Java Localization APIs.
REST Programming
When using the REST API, all data is specified in Database Format:
Field Format Date, DateTime, Time Currency, Number,
Number with Decimal,
Percent- No currency symbol or percent sign
- No grouping characters (e.g. commas) in whole-number portion
- A decimal point (.) before fractional portion
Ex: 84954.32
Lookup - The Record ID of a record in the target object.
Ex: 123A456B78
Multi Object Lookup Ex: 849Z:123A456B78
JavaScript Programming
In general, when coding Field Scripts and Form Scripts, form data will be in the User Format. Coders need to be aware of that fact when doing conversions and calculations, and when entering data into the form -- as the platform expects data coming from the form to be in that format.
However, if the code uses AJAX and REST to interact with the platform, the data going to the platform must be in Database Format, as will the data coming back. That format applies to dates and times, as well as numeric data.
To convert between the formats, use the JavaScript Localization Functions.
Template Programming
For a JSP Page-based template, the Java API described above is used to access record data. In that context, Java rules apply.
In other templates, the Velocity programming language is used.
Most template variables are simply inserted into the template, for inclusion in the final document. Template variable data, therefore, is in User Format. However, sophisticated template developers may use conditions to vary the template content based on record data.
When coding a conditional comparison in Velocity, the condition needs to account for the fact that the record data is in User Format. The mechanism for doing so is the Document Template Class, which lets you preprocess the list of data values, adding to it and modifying as needed, before it is seen by the template.
Note: Data preprocessing is not supported in Email Templates.
With such a class, you can add a new template variable to the record, using the Java Localization Functions to convert record data to Database Format. The template can then use the same format for the comparison value, so you wind up comparing apples to apples.
Of course, you could also convert the comparison value into User Format, and compare oranges to oranges. But then the comparison value would be embedded in the code, where it is harder to change. So the recommended approach is to convert the user data to Database Format.
