First you need to make a copy of the template on which you are going to base your custom template. To do this navigate to the folder where the templates are stored. Assuming MySQL Workbench has been installed into the default location on Windows, this would be C:\Program Files\MySQL\MySQL Workbench 5.0 SE\modules\data\wb_model_reporting.

Then make a copy of the template folder you wish to base your new template on. In this case a copy of the Text_Basic.tpl folder is made. The copy can be given any suitable name, for example, Custom_Basic.tpl.

Now the info.xml file needs to be edited, to reflect your custom template. The unedited file in this case is shown here:

<?xml version="1.0"?>
<data>
  <value type="object" struct-name="workbench.model.reporting.TemplateInfo"
  id="{BD6879ED-814C-4CA3-A869-9864F83B88DF}" struct-checksum="0xb46b524d">
    <value type="string" key="description">A basic TEXT report listing schemata and objects.</value>
    <value type="string" key="name">HTML Basic Frame Report</value>
    <value type="list" content-type="object"
    content-struct-name="workbench.model.reporting.TemplateStyleInfo"
    key="styles">
      <value type="object" struct-name="workbench.model.reporting.TemplateStyleInfo"
      id="{7550655C-CD4B-4EB1-8FAB-AAEE49B2261E}" struct-checksum="0xab08451b">
        <value type="string" key="description">Designed to be viewed with a fixed sized font.</value>
        <value type="string" key="name">Fixed Size Font</value>
        <value type="string" key="previewImageFileName">preview_basic.png</value>
        <value type="string" key="styleTagValue">fixed</value>
      </value>
    </value>
    <value type="string" key="mainFileName">report.txt</value>
  </value>
</data>

Two objects are defined in the file. The TemplateInfo object and the TemplateStyleInfo object. These objects contain information about the template that will be displayed in the DBDoc Model Reporting wizard main screen.

The first thing you need to change are the object GUIDs that are used in the file. In this example there are two that need replacing:

id="{BD6879ED-814C-4CA3-A869-9864F83B88DF}"
...
id="{7550655C-CD4B-4EB1-8FAB-AAEE49B2261E}"

Generate two new GUIDS. This can be done using any suitable command-line tool. There are also free online tools that can be used to generate GUIDs. The info.xml file should then be edited accordingly.

Edit the textual information for the TemplateInfo and TemplateStyleInfo objects to reflect the purpose of the custom template.

The modified file will now look something like the following:

<?xml version="1.0"?>
<data>
  <value type="object" struct-name="workbench.model.reporting.TemplateInfo"
  id="{cac9ba3f-ee2a-49f0-b5f6-32580fab1640}" struct-checksum="0xb46b524d">
    <value type="string"
    key="description">Custom basic TEXT report listing schemata and objects.</value>
    <value type="string" key="name">Custom Basic text report</value>
    <value type="list" content-type="object"
    content-struct-name="workbench.model.reporting.TemplateStyleInfo" key="styles">
      <value type="object"
      struct-name="workbench.model.reporting.TemplateStyleInfo"
      id="{39e3b767-a832-4016-8753-b4cb93aa2dd6}" struct-checksum="0xab08451b">
        <value type="string" key="description">Designed to be viewed with a fixed sized font.</value>
        <value type="string" key="name">Fixed Size Font</value>
        <value type="string" key="previewImageFileName">preview_basic.png</value>
        <value type="string" key="styleTagValue">fixed</value>
      </value>
    </value>
    <value type="string" key="mainFileName">custom_report.txt</value>
  </value>
</data>

The next step is to create the new template file. Again this may best be achieved, depending on your requirements, by editing an existing template. In this example the template file report.txt.tpl is shown here:

+--------------------------------------------+
| MySQL Workbench Report                     |
+--------------------------------------------+

Total number of Schemata: {{SCHEMA_COUNT}}
=============================================
{{#SCHEMATA}}
{{SCHEMA_NR}}. Schema: {{SCHEMA_NAME}}
----------------------------------------------
## Tables ({{TABLE_COUNT}}) ##
{{#TABLES}}{{TABLE_NR_FMT}}. Table: {{TABLE_NAME}}
{{#COLUMNS_LISTING}}## Columns ##
Key  Column  Name  Datatype  Not Null  Default  Comment
{{#COLUMNS}}{{COLUMN_KEY}}{{COLUMN_NAME}}{{COLUMN_DATATYPE}} »
{{COLUMN_NOTNULL}}{{COLUMN_DEFAULTVALUE}}{{COLUMN_COMMENT}}
{{/COLUMNS}}{{/COLUMNS_LISTING}}
{{#INDICES_LISTING}}## Indices ##

{{#INDICES}}{{INDEX_NAME}}{{#INDICES_COLUMNS}}{{INDEX_COLUMN_NAME}} »
{{INDEX_COLUMN_ORDER}}{{INDEX_COLUMN_COMMENT}}{{/INDICES_COLUMNS}} »
{{INDEX_PRIMARY}}{{INDEX_UNIQUE}}{{INDEX_TYPE}}{{INDEX_KIND}}{{INDEX_COMMENT}}
{{/INDICES}}{{/INDICES_LISTING}}
{{#REL_LISTING}}## Relationships ##
Relationship  Name  Relationship  Type  Parent Table  Child Table Cardinality
{{#REL}}{{REL_NAME}}{{REL_TYPE}}{{REL_PARENTTABLE}}{{REL_CHILDTABLE}}{{REL_CARD}}
{{/REL}}{{/REL_LISTING}}
---------------------------------------------

{{/TABLES}}
{{/SCHEMATA}}
=============================================
End of MySQL Workbench Report

This template shows details for all schemata in the model.

The above template file can be edited in any way you like, with new markers being added, and existing markers being removed as required. For the custom template example you might want to create a much simpler template. Such as the one following:

+--------------------------------------------+
| MySQL Workbench Custom Report              |
+--------------------------------------------+

Total number of Schemata: {{SCHEMA_COUNT}}
=============================================
{{#SCHEMATA}}
Schema Name: {{SCHEMA_NAME}}
----------------------------------------------
## Tables ({{TABLE_COUNT}}) ##

{{#TABLES}}
Table Name: {{TABLE_NAME}}
{{/TABLES}}
{{/SCHEMATA}}

Report Generated On: {{GENERATED}}
=============================================
End of MySQL Workbench Custom Report

This simplified report just lists the schemata and the tables in a model. The date and time the report was generated will also be displayed as a result of the use of the {{GENERATED}} variable.

The custom template can then be tested. Start MySQL Workbench, load the model to generate the report for, select the Model, DBDOC - Model Reporting menu item. Then select the new custom template from the list of available templates, select an output directory and then click Finish to generate the report. Finally, navigate to the output directory to view the finished report.
