  • Django1.1 model field value preprocessing before returning

    - by Satoru.Logic
    Hi, all. I have a model class like this: class Note(models.Model): author = models.ForeignKey(User, related_name='notes') content = NoteContentField(max_length=256) NoteContentField is a custom sub-class of CharField that override the to_python method in purpose of doing some twitter-text-conversion processing. class NoteContentField(models.CharField): __metaclass__ = models.SubfieldBase def to_python(self, value): value = super(NoteContentField, self).to_python(value) from ..utils import linkify return mark_safe(linkify(value)) However, this doesn't work. When I save a Note object like this: note = Note(author=request.use, content=form.cleaned_data['content']) note.save() The conversed value is saved into the database, which is not what I wanna see. What I'm trying to do is to save the raw content into the database, and only make the conversion when the content attribute is later accessed. Would you please tell me what's wrong with this? Thanks to Pierre and Daniel. I have figured out what's wrong. I thought the text-conversion code should be in either to_python or get_db_prep_value, and that's wrong. I should override both of them, make to_python do the conversion and get_db_prep_value return the unconversed value: from ..utils import linkify class NoteContentField(models.CharField): __metaclass__ = models.SubfieldBase def to_python(self, value): self._raw_value = super(NoteContentField, self).to_python(value) return mark_safe(linkify(self._raw_value)) def get_db_prep_value(self, value): return self._raw_value I wonder if there is a better way to implement this?

  • Multi choice form field in Django

    - by Dingo
    Hi! I'am developing application on app-engine-path. I would like to make form with multichoice (acceptably languages for user). Code look like this: Language settings: settings.LANGUAGES = ((u"cs", u"Ceština"), (u"en", u"English")) Form model: class UserForm(forms.ModelForm): first_name = forms.CharField(max_length=100) last_name = forms.CharField(max_length=100) languages = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple, choices=settings.LANGUAGES) The form is rendered o.k. (all languages have checkbox. IDs, NAMEs is ok.) But if I save some languages for user, those languages don't check checkboxes. User model look like this class User(User): #... languages = db.StringListProperty() #... and view: def edit_profile(request): user = request.user if request.method == 'POST': form = UserForm(request.POST) if form.is_valid(): # ... else: form = UserForm(instance=user) data = {"user":user, "form": form} return render_to_response(request, 'user_profile/user_profile.html', data)

  • SharePoint's CAML query the "Created By" field with username

    - by yellowblood
    Hey, I have a form for administrators where they insert a user name ("domain\name") and the code gets and sets some information out of it. It's a huge project and some of the lists contain the username as a string ("domain\name"), but some lists only count on the "Created By" column, which is auto-created. I want to know what's the fastest way to query these lists using the username string. I tried to use the same query as the one I use for the first kind of lists and it obviously didn't work - <Where><Eq><FieldRef Name='UserName'/><Value Type='Text'>domain\\username</Value></Eq></Where> Thank you.

  • ASP.NET Binding integer to CheckBox's Checked field

    - by Sung Meister
    I have a following ListView item template, in which I am trying to bind integer value to Checked property of CheckBox. IsUploaded value contains only 0 and 1... <asp:ListView ID="trustListView" runat="server"> <ItemTemplate> <asp:CheckBox ID="isUploadedCheckBox" runat="server" Checked='<%# Bind("IsUploaded") %>' /> </ItemTemplate> </asp:ListView> But ASP.NET complains that Exception Details: System.InvalidCastException: Sepcified cast is not valid Even though following code using DataBinder.Eval() works, I need to have a 2-way binding, thus need to use Bind(). <asp:CheckBox ID="isUploadedCheckBox2" runat="server" Checked='<%# Convert.ToBoolean( DataBinder.Eval(Container.DataItem, "IsUploaded"))) %>' /> How can I convert 0's and 1's to boolean using Bind()? [ANSWER] I have extended auto-generated type through partial class by adding a new property mentioned in the answer by Justin

  • Mysql Real Escape String PHP Function Adding "\" to My Field Entry

    - by Jascha
    Hello, I am submitting a form to my mySql database using PHP. I am sending the form data through the mysql_real_escape_string($content); function. When the entry shows up in my database (checking in myPhpAdmin) all of my double quotes and single quotes are escaped. I'm fairly certain this is a PHP configuration issue? so: $content = 'Hi, my name is Jascha and my "favorite" thing to do is sleep'; mysql_real_escape_string($content); $query = 'INSERT INTO DB...' comes up in my database as: Hi, my name is Jascha and my \"favorite" thing to do is sleep Who do I tell what to do? (I cannot access the php.ini). -J

  • JSP/Servlet CRUD form with special input field based on join table relationship

    - by user1701467
    There's database with a bunch of tables that are joined with join tables. E.g. Members and Division are joined with MembersDivisions table. JSP/Servlet login functionality has been developed, but now the CRUD functionality needs to be implemented and I was unable to find any tutorials about it, especially involving the join table(when creating new division you can add members to it, or add more to the existing one). Maybe someone could, theoretically, explain how to do the Division part of the CRUD web form?

  • CakePHP belongsTo relationship with a variable 'model' field.

    - by gomezuk
    I've got a problem with a belongsTo relationship in CakePHP. I've got an "Action" model that uses the "actions" table and belongs to one of two other models, either "Transaction" or "Tag". The idea being that whenever a user completes a transaction or adds a tag, the action model is created to keep a log of it. I've got that part working, whenever a Transaction or Tag is saved, the aftersave() method also adds an Action record. The problem comes when I try to do a find('all') on the Action model, the related Transaction or Tag record is not being returned. actions: id model model_id created I thought I could use the "conditions" parameter in the belongsTo relationship like this: <?php class Action extends AppModel { var $name = 'Action'; var $actsAs = array('Containable'); var $belongsTo = array( 'Transaction' => array( 'foreignKey' => 'model_id', 'conditions' => array("Action.model"=>"Transaction") ), 'User' => array( 'fields' => array('User.username') ), 'Recommendation' => array( 'conditions' => array("Action.model"=>"Recommendation"), 'foreignKey' => 'model_id' ) ); } ?> But that doesn't work. Am I missing something here, are my relationships wrong (I suspect so)? After Googling this problem I cam across something called Polymorphic Behaviour but I'm not sure this will help me.

  • Hibernate: @UniqueConstraint with @ManyToOne field???

    - by Misha Koshelev
    Dear All: Using the following code: @Entity @Table(uniqueConstraints=[@UniqueConstraint(columnNames=["account","name"])]) class Friend { @Id @GeneratedValue(strategy=GenerationType.AUTO) public Long id @ManyToOne public Account account public String href public String name } I get the following error: org.hibernate.AnnotationException: Unable to create unique key constraint (account, name) on table Friend: account not found It seems this has to do with the @ManyToOne constraint, which I imagine actually creates a separate UniqueConstraint??? In any case, if I take this out, there is no complaint about the UniqueConstraint, but there is another error which makes me believe it must be left in. org.hibernate.MappingException: Could not determine type for: com.mksoft.fbautomate.domain.Account, at table: Friend, for columns: [org.hibernate.mapping.Column(account)] Any hints how I can create such a desired constraint (i.e., that each combination of account and name occurs only once???) Thank you! Misha

  • Java printf using variable field size?

    - by paxdiablo
    I'm just trying to convert some C code over to Java and I'm having a little trouble with String.printf. In C, to get a specific width based on a variable, I can use: printf("Current index = %*d\n", sz, index); and it will format the integer to be a specific size based on sz. Trying: System.out.println(String.format("Current index = %*d\n", sz, index)); results in an error since it doesn't like the *. I currently have the following kludge: System.out.println(String.format("Current index = %" + sz + "d\n", index)); but I'm hoping there's a slightly better way, yes?

  • How to make a Django model fields calculated at runtime?

    - by Anatoly Rr
    I have a model: class Person (models.Model): name = models.CharField () birthday = models.DateField () age = models.IntegerField () I want to make age field to behave like a property: def get_age (self): return (datetime.datetime.now() - self.birthday).days // 365 age = property (get_age) but at the same time I need age to be a true field, so I can find it in Person._meta.fields, and assign attributes to it: age.help_text = "Age of the person", etc. Obviously I cannot just override Person.save() method to calculate and store age in the database, because it inevitably will become wrong later (in fact, it shouldn't be stored in the database at all). Actually, I don't need to have setters now, but a nice solution must have setting feature. Is it possible in Django, or probably there is a more pythonic and djangoic approach to my problem?

  • SSRS function returns #Error if value of field is null

    - by jen-fields
    Thanks in advance for any and all assistance. My code is: Public Function StripHTML(value As String) As String Return System.Text.RegularExpressions.Regex.Replace(value, "<(.|\n)*?", "") End Function Then I call the function from a textbox. This works great unless there are nulls in the dataset. I tried to compensate for the nulls, but the RDLC file generates an error message that it can't display the subreport. Public Function StripHTML(value As String) As String if isnothing(value) then return value else Return System.Text.RegularExpressions.Regex.Replace(value, "<(.|\n)*?", "") end if End Function I also tried to tell it to return " " if null. I had no luck... Any ideas? and thanks again.

  • who do you admire in a scientific/technical field [closed]

    - by Tshepang
    This off-topic item refers to people with major achievements in fields such as engineering, science, and mathematics. Here's my picks: Eric Drexler for his work on molecular nanotech. His book, Engines of Creations, is mind-blowing. Robert Freitas for his work on molecular nanotech. The breadth of his multi-volume book, Nanomedicine, is impressive. Richard Stallman for promoting Free Software.
