• Error handling with Python + Pylons

  - by ensnare

  What is the proper way to handle errors with Python + Pylons? Say a user sets a password via a form that, when passed to a model class via the controller, throws an error because it's too short. How should that error be handled so that an error message gets displayed on the web page rather than the entire script terminating to an error page? Should there be any error handling in the controller itself? I hope I am explaining myself clearly. Thank you.

• Using non-Railsy route to prepopulate a form

  - by user94154

  I have many instances of a Rails model, Post. When viewing an individual post, I'd like to create a form to create a child of Post called Comment. I'd like to prepopulate this form with a hidden tag that contains the post_id which is the foreign key in Comment. The Railsy way to do this is to create a fancy-ish route such as: /comments/new/post/:post_id However, this gunks up the routes file and doesn't leave much flexibility. Let's say I want to create a link somewhere else that prepopulates a different attribute of the form...then I'd have to add another route for this. So I think I'm going to create urls like this on /posts/show/:id: /comments/new?comment[post_id]=<%= @post.id %> This way I can add any other attributes as I need. I know the plus side associated with this, now what are the downsides?

• Django : looking for a good LDAP manipulation library

  - by sebpiq

  Hi ! I am looking for a good ldap library on Django, that would allow me to manage my ldap server : adding, modifying, deleting entries for groups, users, and all kind of objects The library django-ldapdb looked promising, it offers a Model base class that can be used to declare ldap objects in a Django fashion (which is what we ideally want), however we've had some bugs with it, and furthermore it seems like it is not maintained any more. Does somebody know a good library that could do the trick ? Otherwise I guess I'll just try to improve and debug django-ldapdb ... Thanks !

• Pattern for unidirectional has_many join?

  - by Kris

  It occurred to me that if I have a has_many join, where the foreign model does not have a belongs_to, and so the join is one way, then I don't actually need a foreign key. We could have a column, category_ids, which stores a marshaled Array of IDs which we can pass to find. So here is an untested example: class page < AR def categories Category.find(self.category_ids) end def categories<<(category) # get id and append to category_ids save! end def category_ids @cat_ids ||= Marshal.load(read_attribute(:category_ids)) rescue [] end def category_ids=(ids) @cat_ids = ids write_attribute(:category_ids, ids) end end page.category_ids = [1,4,12,3] page.categories = Array of Category Is there accepted pattern for this already? Is it common or just not worth the effort?

• What is the difference between "render a view" and send the response using the Response's method "sendResponse()"?

  - by Green

  I've asked a question about what is "rendering a view". Got some answers: Rendering a view means showing up a View eg html part to user or browser. and So by rendering a view, the MVC framework has handled the data in the controller and done the backend work in the model, and then sends that data to the View to be output to the user. and render just means to emit. To print. To echo. To write to some source (probably stdout). but don't understand then the difference between rendering a view and using the Response class to send the output to the user using its sendResponse() method. If render a view means to echo the output to the user then why sendResponse() exists and vise versa? sendResponse() exactly sends headers and after headers outputs the body. They solve the same tasks but differently? What is the difference?

• How can I ask Hibernate to create an index on a foreign key (JoinColumn)?

  - by Kent Chen

  Hi, This is my model. class User{ @CollectionOfElements @JoinTable(name = "user_type", joinColumns = @JoinColumn(name = "user_id")) @Column(name = "type", nullable = false) private List<String> types = new ArrayList<String>(); } You can imagin there would be a table called "user_type", which has two columns, one is "user_id", the other is "type". And when I use hbm2ddl to generate the ddls, I can have this table, along with the foreign key constraint on "user_id". However, there is no index of this for this column. And I need this index. How can I let hibernate to generate this index for me? Thank you!

• Create MVC 5 Combo Box from CRM Entities?

  - by SpaceCowboy74

  I am working on an MVC 5 App that pulls data from Dynamics CRM 5. The Data I am getting back is an IQueryable of type Account (The CRM Entity class auto generated by CrmSvcUtil). I am retrieving all of the items and can loop through them with code like this: @foreach (var item in Model.ToList()) { <tr> <td> @item.AccountId </td> <td> @Html.DisplayFor(modelItem => item.Name) </td> </tr> } The problem is, I would like to instead put them in a drop down list. I can't figure out what the syntax is to put these in a DropDown is. Any suggestions?

• jquery integrate form parameter in one object

  - by jesse

  There are many forms in my page. I want to merge them in one object and submit them in one object. But I find serializeArray() or serialize() do not match my request, the serializeArray function will generate a array object and serialize is used by get model, it is not an object. is there a jquery or local function can merge them in one object. I have one solution but it is not perfect, loop the array object generated by serializeArray, use $.extend to merge them in one object. is there a better method? kindly help, thanks.

• Own params to PeriodicTask run() method in Celery

  - by Alex Isayko

  Hello to all! I am writing a small Django application and I should be able to create for each model object its periodical task which will be executed with a certain interval. I'm use for this a Celery application, but i can't understand one thing: class ProcessQueryTask(PeriodicTask): run_every = timedelta(minutes=1) def run(self, query_task_pk, **kwargs): logging.info('Process celery task for QueryTask %d' % query_task_pk) task = QueryTask.objects.get(pk=query_task_pk) task.exec_task() return True Then i'm do following: >>> from tasks.tasks import ProcessQueryTask >>> result1 = ProcessQueryTask.delay(query_task_pk=1) >>> result2 = ProcessQueryTask.delay(query_task_pk=2) First call is success, but other periodical calls returning the error - TypeError: run() takes exactly 2 non-keyword arguments (1 given) in celeryd server. So, can i pass own params to PeriodicTask run() ? Thanks!

• Password Hash Implementation

  - by oyerli

  I am developing a new application using Symfony. I want to store the passwords hashed, so I overridded the save method in my User model: public function save(Doctrine_Connection $conn = null) { $this->setUserPassword( md5($this->getUserPassword()) ); return parent::save($conn); } This works good when a new user created. However, this causes problems when we edit a user without changing his password. This causes Doctrine to hash the already hashed password. So, I need to check that whether the UserPassword is modified in this DoctrineRecord instance. How can I manage to do that?

• Need advice on multitab form in ASP.NET MVC

  - by Sasha

  Hi all, i need an advice on how to implement my form. I have a requirement: i need a form that spans through 5 tabs. Each tab has around 10 fields, some of them empty, some of them must contain data from db and be non editable. Each of these tabs must be a part of one form that is submitted to my controller. The question is: what is the best way to implement this? I was thinking about having partial views on each tab, each view would have its own model class. After form gets filled all data from all partials would go to action that will take care of all of it. Any advices? I am using ASP.NET MVC 1, Entity Framework 1, mvc extensions from Telerik and jQuery

• Class views in Django

  - by Sebastjan Trepca

  Django view points to a function, which can be a problem if you want to change only a bit of functionality. Yes, I could have million keyword arguments and even more if statements in the function, but I was thinking more of an object oriented approach. For example, I have a page that displays a user. This page is very similar to page that displays a group, but it's still not so similar to just use another data model. Group also has members etc... One way would be to point views to class methods and then extend that class. Has anyone tried this approach or has any other idea?

• Can’t dup NilClass - how to trace to offender

  - by fullware

  This exception occurs often and intermittently when in development mode, and appears to get triggered by model associations. Does There are lots of references found by google but none seem to help to trace the problem to an offending class. Does anyone have any insight into how to trace the occurrence of this exception to it's cause? I've seen the posts on adding "unloadable" but I'm not sure I buy it--unless there's a way to trace it somehow to its cause. I'm not in favor of indiscriminately adding such things to every class in hopes the problem might go away. Rails 2.3.5.

• Change list link to foreign key change page

  - by Adam

  When viewing the admin change list for a model, is it possible to make the columns that correspond to foreign keys links to their respective pages? A simple example is I have a Foo object which contains Bar as a foreign key. If I'm viewing the admin change list for Foo (and have it set to include Bar in the display_list columns), the main column would link to the Foo instance's edit page while the Bar column would link to the Boo instance's edit page. I understand I can override the template that's used, but I was curious if there was a solution that didn't require that.

• Rails modeling for a user

  - by Trevor Hartman

  When building a rails app that allows a User to login and create data, is it best to setup a belongs_to :user association on every single model? For example, let's say a user can create Favorites, Colors and Tags. And let's say Favorites has_many :tags and Colors also has_many :tags. Is it still important for Tags to belong_to :user assuming the User is the only person who has authority to edit those tags? And a similar question along the same lines: When updating data in FavoritesController, I've come to the conclusion that you perform CRUD operations by always doing something like User.favorites.find(params[:id].update_attributes(param[:favorite]) so that they can definitely only update models that belong to them. Right?

• Django: how to pass form variable to simple tag in template

  - by Remigijus

  Hello. I am trying to do some custom things in Django comments form. I have simple tag named "get_flatpage_by_id" that returns flatpage model data as array. This is working I expected: {% get_flatpage_by_id 14 as page %} It's returning flatpage that ID is 14. But this is not working, if I try to pass {{ form.object_pk.data }} (that returns 14). This is how it should look like: {% get_flatpage_by_id form.object_pk.data as page %} Simple tag receives value "form.object_pk.data" (string), not 14. I don't know how to tell Django that "form.object_pk.data" is variable, not a string!

• rails 3.1 partial_updates doesn't seem to work with password

  - by user1306769

  i have a user model with a password attribute, which gets saved as password_digest. What i want to do is have the edit user page and the edit password page separated, so that the admin doesn't need to input the password everytime he needs to change something else. For this i have made an extra action / view. My problem is that when i update the user info, i get password validation errors even though i have no password field in the form. Which leads me to the conclusion that partial_updates isn't working with the password attribute (as i have already tested in the console that it is enabled, and it is) Is this me doing something wrong, or should i approach this differently?
