| 5 | ~~~~~~~~~~~~~~~~~~~~~~~~~~ |
|---|
| 6 | |
|---|
| 7 | We have two kinds of forms: POST actions and GET actions |
|---|
| 8 | POST actions are: |
|---|
| 9 | - filemanager.action_mkdir() |
|---|
| 10 | - filemanager.action_fileupload() |
|---|
| 11 | - filemanager.action_rmdir() |
|---|
| 12 | - filemanager.action_deletefile() |
|---|
| 13 | GET actions are: |
|---|
| 14 | - filemanager.edit() (Edit a text file) |
|---|
| 15 | |
|---|
| 16 | POST action note: |
|---|
| 17 | The POST actions used a hidden field named "action" for easy differ |
|---|
| 18 | the the current action in the POST data. See below the constants. |
|---|
| 19 | GET action notes: |
|---|
| 20 | - The GET forms should not insert a field named "action"! |
|---|
| 21 | - After a finished GET method, it should display the filelist(). |
|---|
| 22 | |
|---|
| 23 | |
|---|
| 24 | restrictions: |
|---|
| 25 | - Only tested under linux! |
|---|
| 26 | |
|---|
| 27 | TODO: |
|---|
| 28 | - should use posixpath for every URL stuff. |
|---|
| 29 | - deny editing of binary files (how? ext whitelist or using file?) |
|---|
| 30 | - insert the basepath selection into the filelist view. |
|---|
| 31 | - find a way to reduce the redundance. |
|---|
| 32 | - Write a unitest for the plugin and verify the "bad-char-things" in |
|---|
| 33 | path/post variables. |
|---|
| 34 | - Fixe some unicode problems: |
|---|
| 35 | e.g.: upload a file with a non ascii content |
|---|
| 36 | use sys.getfilesystemencoding() ? |
|---|
| 37 | - Check the Plugin under windows - very low priority :) |
