Filtering Data

Filtering Data

Follow the following recommendations when creating a new data set:
  1. Follow general XML formatting rules.
  2. Use &amp to get ampersands &.

    Follow the same rule for other special characters.

  3. Avoid using angle brackets or <element> tags as placeholder values.
  4. Use '\\' instead of backslashes ('\').

Placeholder values in data sets are filtered by data population before the database update occurs. This provides a consistent way to define environment-specific values for both SQL and import/export files.

Placeholders values are configured in the database/ext-data module in the following files:
File Description
resources/config/filtering.properties Specifies the default values that are shared by all environments. You can override these values in environment-specific property files.
resources/environments/*/filtering.properties Specifies environment specific property values. Each environment has its own filtering.properties file. For example, environments/local/filtering.properties
  1. To create a new placeholder in a data sets, add the placeholder to data using the spring-style placeholder.
    For more information, see Data filtering (property placeholders).
  2. Optional: Add the default value for the place holder to the filtering.properties file.
  3. Add environment-specific values to filtering.properties files in each environment directory if the values differ from the default values.
    Note:

    Elastic Path recommends does not recommend using default values and to add environment-specific values for all environments. If you do not define an environment-specific value, the default value, localhost, is used.

In this example, the placeholder ${ep.smtp.host} is defined in an import/export data file with a default value as localhost.
<configuration_setting>
    <name_space>COMMERCE/SYSTEM/EMAIL/mailHost</name_space>
    <default_value type="String">${ep.smtp.host:localhost}</default_value>
    ...
</configuration_setting>
You can replace the default value with the following environment-specific values. For example:
Environment Value Notes
local ep.smtp.host=${ep.smtp.host} Uses the value of ep.smtp.host defined in the .m2/settings.xml file.
qa ep.smtp.host=smtp-test.company.com Uses the test SMTP server URL.
prod-live ep.smtp.host=smtp.company.com Use the production SMTP server URL.
