| 2135 Actions may return content to the user | |
| 2136 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
| 2137 | |
| 2138 Actions generally perform some database manipulation and then pass control | |
| 2139 on to the rendering of a template in the current context (see `Determining | |
| 2140 web context`_ for how that works.) Some actions will want to generate the | |
| 2141 actual content returned to the user. Action methods may return their own | |
| 2142 content string to be displayed to the user, overriding the templating step. | |
| 2143 In this situation, we assume that the content is HTML by default. You may | |
| 2144 override the content type indicated to the user by calling ``setHeader``:: | |
| 2145 | |
| 2146 self.setHeader('Content-Type', 'text/csv') | |
| 2147 | |
| 2148 This example indicates that the value sent back to the user is actually | |
| 2149 comma-separated value content (eg. something to be loaded into a | |
| 2150 spreadsheet or database). | |
