Is there such a thing?

• how to add a dynamic param

  - by user569846

  the jquery plugin that im using is this http://code.google.com/p/jquery-in-place-editor/ if i have a table like this <table> <thead> <tr> <th>id</th> <th>first name </th> <th>last name </th> </tr> </thead> <tbody> <tr> <td class="id">1</td> <td class="fname">sarmen</td> <td class="lname">mikey</td> </tr> <tr> <td class="id">2</td> <td class="fname">john</td> <td class="lname">angelo</td> </tr> <tr> <td class="id">3</td> <td class="fname">sarmen</td> <td class="lname">grande</td> </tr> </tbody> </table> and my js looked something like this $("td.fname").editInPlace({ url: 'ajax.php', params: '', show_buttons: true }); then lets say i click on the first record to edit it which is fname of sarmen. how can i pass a param that only accociates id 1 ? because if i do a query of lets say "update tbl_users set fname = '$_POST['update_value']' where fname = '$_POST['original_html']'" (note: im just showing an example so no need to clean posts if that was bothering you :) ) if i run this query the fname of sarmen will update in two records rather than one. How can i only update to id of 1 being to update only one record.

• Why would restarting MySQL make my site faster?

  - by beagleguy

  hey all, my site started dragging lately, the queries taking exceptionally longer than I would expect with properly tuned indexes. I just restarted the mysql server after 31 days uptime and every query is now substantially faster and the whole site renders 3-4 times faster. Would there be anything that jumps out at you as to why this may have been? Improper settings on my.cnf perhaps? Any ideas as to what I can start looking at to try and pinpoint why? thanks

  Currently my login controller doesn't work because i can't seem to fetch the username and password. I'm currently using something like this: form_username = str(request.params.get('username')) db_user = meta.Session.query(User).filter_by(username=form_username) if db_user is None: return redirect('auth/error') No matter which username is use, db_user always returns True and thus never goes to auth/error. I used the shell to play with this and i was able establish a connection with the database, so i'm not sure what i'm doing wrong here.
