• Server not receiving data from client

  - by Ronald

  I have a small server application I wrote in Java running on my web server. The client application I wrote can connect to the server and it receives data, but the server does not receive any data sent by the client. Any idea what the problem could be? The two communicate fine on my local machine.

• Efficient way to update SQL 'relationship' table

  - by AmbroseChapel

  Say I have three properly normalised tables. One of people, one of qualifications and one mapping people to qualifications: People: id | Name ---------- 1 | Alice 2 | Bob Degrees: id | Name --------- 1 | PhD 2 | MA People-to-degrees: person_id | degree_id --------------------- 1 | 2 # Alice has an MA 2 | 1 # Bob has a PhD So then I have to update this mapping via my web interface. (I made a mistake. Bob has a BA, not a PhD, and Alice just got her B Eng.) There are four possible states of these one-to-many relationship mappings: was true before, should now be false was false before, should now be true was true before, should remain true was false before, should remain false what I don't want to do is read the values from four checkboxes, then hit the database four times to say "Did Bob have a BA before? Well he does now." "Did Bob have PhD before? Because he doesn't any more" and so on. How do other people address this issue? I'm curious to see if someone else arrives at the same solution I did.

• how to prevent divs from overlapping when using no-wrap across table cells

  - by pedalpete

  I'm trying to create an events calendar which has a somewhat 'gantt' chart like bar representing the times of an event, along with the time listed. I've uploaded a page showing the problem As you can see, the problem is that in the 3rd cell, the event div is being overlapped by the previous event div which goes outside the boundary of the cell. The event from the 2nd cell SHOULD expand beyond the cell border, but what I'm trying to get to happen is that WHEN the event from the 2nd cell expands into the 3rd cell, the event on the 3rd cell starts a new line. I believe the problem exists because of the nowrap on the time, but I want the time and in some cases the bar to cross the cell boundary when the time goes from one day to another. All that works now, but I'm having a problem with events overlapping when an event goes from one day to another. I've tried all sorts of :even cells having a different padding, etc. but all these solutions seem to bring up more problems. Is there a way get the no-wrap to force a new long when it crosses into the next cell? or any other solution to this issue?

• Custom data forms in CakePHP

  - by Affian

  I'm building a controller to manage group based ACL in CakePHP and when I create or edit a group I want to be able to select what permissions it has. The group data table only stores a group ID and a group Name as the permissions are stored in the ACO/ARO table. I have an array from the ACO that I want to turn into a set of checkboxes so you can check them to allow access from that group to that ACO. So first off, how do I turn this array into a set of checkboxes. The array looks like this: array( [0] => array( [Aco] => array( [alias] => 'alias' [id] => 1) [children] => array ( [0] => array( [Aco]=> ...etc )) [1] => array( ...etc ) My next question is how can I check these once the form has been submitted to the controller to allow the selected actions? [Update] Ok changing the angle of my question, how can I use the Form helper to create forms that are not based on any Model?

• JPA Secondary Table Issue

  - by Smithers

  I have a three tables: User, Course, and Test. Course has a User foreign key and Test has a Course foreign key. I am having trouble mapping the Test collection for each User since I need an intermediary step from User - Course - Test. I am trying to use a SecondaryTable since the User key for the Test is its associated Course row. Am I on the right track using SecondaryTable or is there a way to use a JoinTable without the inverseJoinColumn?

  Is there a way to sort Devexpress QuantumGrid rows on data from a different column other than the one whose header has been clicked? For example, when the header of column A is clicked the rows of the grid are sorted on the data from column B. Visually it should still appear that it is column A that has been sorted as the sort glyphys will be shown in column A's header.

  Hi, This part is from views.py results=[(A,[stuObj1,stuObj2,stuObj3]),(B,[stuObj4,stuObj5,stuObj6]),(C,[stuObj7,stuObj8])] for tup in results: total = tot+len(tup[1]) render_to_response(url,{'results':res , 'total':str(tot),}) this is template code: <th class="name">Name</th> <th class="id">Student ID</th> <th class="grade">Grade</th> {% for tup in results %} {% for student in tup|last %} {% with forloop.parentloop.counter as parentid%} {% with forloop.counter as centerid%} <tbody class="results-body"> <tr> <td>{{student.fname|lower|capfirst}} {{student.lname|lower|capfirst}}</td> <td>{{student.id}}</td> <td>{{tup|first}}</td> </tr> {% endfor %} {% endfor %} Now the problems am having are 1. numbering the rows. Here my problem is am not sure if i can do things like total=total-1 in the templates to get the numbered rows like <td>{{total}}</td> 2.applying css to tr:ever or odd. Whats happening in this case is everytime the loop is running the odd/even ordering is lost. these seems related problems. Any ideas would be great :)
