#### 7/3/2017 INSTRUCTION FILES - DISPLAYED IN VIEW MODE
 
## MIGRATION
#### Instruction Files migration from outside ILIAS directory to ILIAS "data" directory
 
File -> **patch_exc_move_instruction_files.php**
 
I assume that all the files located in "ass_XXX" --> outside ilias /outside_data_directory/client_name/ilExercise/X/exc_XXX/ass_XXX/0
are instruction files.
 
We had doubts about where are the solution files located and this files are located in directories like this: feedb_xx/0/xxxx.xx
 
So The patch moves all the content in ass_ directories.
 
 
## FEATURE IMPLEMENTATION
Save and show instruction files located inside root directory instead of outside data directory.
 
        - (edit) **include/inc.ilias_version.php** change ILIAS version
 
                        define("ILIAS_VERSION", "5.3.0 2017-02-07");
                        define("ILIAS_VERSION_NUMERIC", "5.3.0");
 
        - (new class) **Modules/Exercise/classes/class.ilFSWebStorageExercise.php** extending ilFileSystemStorage class.
        Stores the files inside ILIAS data directory.
        important to know, in the construct:
 
                parent::__construct(self::STORAGE_WEB,true,$a_container_id);
 
 
        - (edit) **Modules/Exercise/classes/class.ilExerciseExporter.php**
 
                - (edit)**getValidSchemaVersions()** method: Add new ILIAS version
 
                                "5.2.0" => array(
                                "namespace" => "http://www.ilias.de/Modules/Exercise/exc/5_2",

## MANTIS BUG :0019795
It is not possible to remove files from a peer feedback from a exercise.
 
 
The problem seems the file path creation and affects both feedback with and without criteria.
 
Example:
User ID who did the exercise: 310
User ID who provide feedback: 6
Feedback file: feedback.txt
Criteria ID = 10
 
Without criteria the uploaded files are stored outside the final path. The name of the file is also affected.
 
data/client/ilExercise/3/exc_343/peer_up_15/310/6/ [empty directory]
data/client/ilExercise/3/exc_343/peer_up_15/310/6feedback.txt
 
After patch:
 
data/client/ilExercise/3/exc_343/peer_up_15/310/6/feedback.txt
 
 
With criteria, the final directory name is userid+criteriaid instead of criteria id.
 
data/client/ilExercise/3/exc_343/peer_up_15/310/610/feedback.txt
 
After patch:
 
data/client/ilExercise/3/exc_343/peer_up_15/310/6/10/feedback.txt
 
## We need to take a look at how to proceed with the migration of the old directories/files.
 
 
 
- Modules/Exercise/classes/class.ilExAssignmentEditorGUI.php
working with ilExAssignmentFileSystemGUI instead of ilFileSystemGUI
 
 
- Modules/Exercise/classes/class.ilExAssignment.php (create another class for this stuff could be fine)
Edit function saveAssOrderOfExercise -- now is static ( fixing another bug )
New function saveInstructionFilesOrderOfAssignment (db update)
New function instructionFileInsertOrder (db store)
New function instructionFileDeleteOrder (db delete)
New function renameInstructionFile (db delete/update)
New function instructionFileExistsInDb (db query)
New function instructionFileAddOrder: DB query and add order to an array previous to setData in the view rows. If the files doesn't have any previous order in the database
        this method will create it so we don't need any patch for the current installations and for the unziping files neither. See instructionFileGetFileOrderData method.
 
New function instructionFileOrderGetMax (db query, max order)
New function instructionFileRearrangeOrder rebuild the order after deletion. example: 10,30,50 will show 10,20,30
New function renameExecutables (names with extensions like php,php3,inc,lang... will be renamed (.sec) after store it in db) //have we another method that renames the extension files in db?
New function instructionFileGetFileOrderData (db query returns order values.)
 
 
 
- Services/FileSystem/classes/class.ilFileSystemGUI.php
Edit Construct commands available are now in the defineCommands method.
Edit ListFiles now can get class name as a param, to use one ilFileSystemTableGUI as always or another.
New function defineCommands define which commands are available.
New function getActionCommands  returns the commands array.
 
 
- Services/FileSystem/classes/class.ilFileSystemTableGUI.php
Edit contructor using the new method addColumns.
Edit function prepareOutput, take an array from getEntries and if the method instructionFileAddOrder exists then
the order values are added to the array.
Edit function getEntries, now doesn't setData, only returns the array to work with.
New function addColumns, check if the property add_order_column from a child class exists and add the proper columns.
Edit function fillRow, check if the property add_order_column from a child class exists and add set the tpl vars.
 
 
 
- Services/FileSystem/templates/default/tpl.directory_row.html
New block: Order
 
- (NEW FILE) Modules/Exercise/classes/class.ilExAssignmentFileSystemGUI.php
Extends Services/FileSystem/classes/class.ilFileSystemGUI.php
- (NEW FILE) Modules/Exercise/classes/class.ilExAssignmentFileSystemTableGUI.php
Extends Services/FileSystem/classes/class.ilFileSystemTableGUI.php
 
 
## Things to take care.
If an assignment is deleted, we should delete the filenames from exc_ass_file_order table.
We are working with this files in the DB with "filename" instead of "id"
 
 
## 2/2/2017
 
*Modules/Exercise/classes/class.ilExSubmissionObjectGUI.php (User perspective)
 
        -(change) method "getOverviewContentPortfolio"
        Button create portfolio in assignment calls now "createPortfolioFromAssignmentObject" instead of getting the templates and createPortfolio.
        If this assignment has one previous submission, one new button are shown to unlink this portfolio/submission (method askUnlinkPortfolio).
 
        *** Here imo we should delete the button for portfolio selection. Because the portfolio is not defined here.
 
-(new) method "askUnlinkPortfolioObject"
        Confirmation for unlink portfolio/assignment.
 
-(new) method "unlinkPortfolioObject"
        Delete the portfolio from the assignment.
 
-(new) method "createPortfolioFromAssignmentObject"
        Check portfolio templates available and check if this assignment has port. template.
        Takes the values from the exercise, assignment, portfolio and portfolio template and set the proper parameters.
        Redirects to createPortfolioFromAssignment in ilObjPortfolioGUI.
 
 
*Modules/Portfolio/classes/class.ilObjPortfolioGUI.php  (assignment submission)
 
-(new) method "createPortfolioFromAssignment" to create portfolios from assignments without cross any form
        check again the templates
        getAllPortfolioPages and get blogs as well.
        create new portfolio and clone pages and blogs from the template.
        link the portfolio to the assignment.
 
-(new) method "linkPortfolioToAssignment"
        Add the portfolio to an assignment
 
-(change) method "createPortfolioFromTemplateProcess"
        now the part related with the portfolio assignment is in linkPortfolioToAssignment method.
 
-(change) initCreatePortfolioFormTemplate
        all the skills stuff moved to getSkillsToPortfolioAssignment method.
 
-(new) method getSkillsToPortfolioAssignment
        returns the skills to be added in the assignment.
 
*Modules/Exercise/classes/class.ilExAssignmentEditorGUI.php
 
-(change) @ilCrl Calls also ilPropertyFormGUI class
 
-(change) method "executeCommand"
        new case "ilpropertyformgui" needed for ilRepositorySelector2 when selection of portfolio template is needed.
 
-(change) method "initAssignmentForm"
        new portfolio feature. radiobuttons + ilrepositoryselector2 to predefine a default portfolio template for this assignment.
        improved the order of the form elements + added section headers.
 
-(change) method "processForm"
        now gets the template input from the form.
 
-(change) method "importFormToAssignment"
        sets the portfolio template id.
 
-(change) method "getAssignmentValues"
        takes the portfolio template id
 
*Modules/Exercise/classes/class.ilExAssignmentGUI.php
just ordering ui elements
 
*Modules/Exercise/classes/class.ilExSubmissionFileGUI.
-(change) method "getOverviewContent"
list files one below another instead of separated by coma.

## ilTextareaInput - MIN and MAX CHARACTER LIMITATIONS.
 
Textarea input now can limit the number of characters allowed. The limitations are not mandatory, for instance we can limit only min or max.
 
## Info to extend this feature to another elements taking exercise assignments as an example.
 
#### DATABASE
 
        update table [X] with 2 new columns "min_char_limit" and "max_char_limit" both integer and length 4.
 
        if($ilDB->tableExists("[table_name]"))

                {
                        $ilDB->addTableColumn("[table_name]", "min_char_limit", array("type" => "integer", "length" => 4));
                }
