  • How does one dismantle the ThinkPad Mini Dock Series 3 (model 4337)?

    - by Whaa
    I have a ThinkPad Mini Dock Series 3 with a spring that is too stiff, causing problems with the connectivity when a computer is docked. I tried to open it so that I can soften the spring, but hit a brick wall. I removed all the screws I could find at the the bottom and the back panel of the docking station, but the bottom part of the plastic case would still not part from the top of the plastic case. I even looked under some of the various stickers for more screws, but found nothing. Can anyone please help with pointers on dismantling this docking station?

  • Query on MVVM pattern in WPF?

    - by Ashish Ashu
    I am implementing a MVVM pattern in my WPF application. My application main window is divided into four parts: Main Menu On the Top Outlook Navigation Control on the Left. A List View on the Middle. Another List view on the bottom. The Navigation control shows different setting (configuration) controls in the Tab items. All the four above are user controls which are placed in the main window. And corresponding to each user control there is separate view model which is bounded with a view model in the XAML of each control, however the model class remain the same between all the view model. And a MainWindow has a seperate View Model which is also bounded with a view model in the XAML of each control. Please help me out in framing a design in which each view models of all the controls above will interact with each other. Please let me know if my question is not clear to you!!

  • Dynamic attributes with Rails and Mongoid

    - by japancheese
    Hello, I'm learning MongoDB through the Mongoid Ruby gem with Rails (Rails 3 beta 3), and I'm trying to come up with a way to create dynamic attributes on a model based on fields from another model, which I thought a schema-less database would be a good choice for. So for example, I'd have the models: class Account include Mongoid::Document field :name, :type => String field :token, :type => String field :info_needed, :type => Array embeds_many :members end class Member include Mongoid::Document embedded_in :account, :inverse_of => :members end I'm looking to take the "info_needed" attribute of the Account model and created dynamic attributes on the Member model based on what's inside. If club.info_needed was ["first_name", "last_name"], I'm trying to create a form that would save first_name and last_name attributes to the Member model. However, upon practice, I just keep getting "undefined method first_name=" errors on the Member model when trying to do this. I know MongoDB can handle dynamic attributes per record, but how can I get Mongoid to do this without an undefined method error?

  • Instance validation error: '2' is not a valid value for QueryType. (web service)

    - by Anthony Shaw
    I have a web service that I am passing an enum public enum QueryType { Inquiry = 1 Maintainence = 2 } When I pass an object that has a Parameter of QueryType on it, I get the error back from the web service saying that '2' is not a valid value for QueryType, when you can clearly see from the declaration of the enum that it is. I cannot change the values of the enum because legacy applications use the values, but I would rather not have to insert a "default" value just to push the index of the enum to make it work with my web service. It acts like the web service is using the index of the values rather than the values themselves. Does anybody have a suggestion of what I can do to make it work, is there something I can change in my WSDL?

  • In Django, can you add a method to querysets?

    - by Paul D. Waite
    In Django, if I have a model class, e.g. from django.db import models class Transaction(models.Model): ... then if I want to add methods to the model, to store reasonably complex filters, I can add a custom model manager, e.g. class TransactionManager(models.Manager): def reasonable_complex_filter(self): return self.get_query_set().filter(...) class Transaction(models.Model): objects = TransactionManager() And then I can do: >>> Transaction.objects.reasonably_complex_filter() Is there any way I can add a custom method that can be chained to the end of a query set from the model? I.e. add the custom method in such a way that I can do this: >>> Transaction.objects.filter(...).reasonably_complex_filter()

  • Django IN query as a string result - invalid literal for int() with base 10

    - by bmelton
    Trying to query a 'Favorites' model to get a list of items a user has favorited, and then querying against a different model to get the objects back from that query to present to the template, but I'm getting an error: "invalid literal for int() with base 10" Looking over all of the other instances of that error, I couldn't find any in which the asker actually wanted to work with a comma separated list of integers, so I'm kind of at a loss. Model class Favorite(models.Model): # key should be the model name, id is the model.id, and user is the User object. key = models.CharField(max_length=255, unique=True) val = models.IntegerField(default=0) user = models.ForeignKey(User) class Admin: list_display = ('key', 'id', 'user') View def index(request): favorites = Favorite.objects.filter(key='blog', user=request.user.pk) values = "" for favorite in favorites: values += "%s," % favorite.val #values = "[%s]" % values blogs = Blog.objects.filter(pk__in=values) return render_to_response('favorite/index.html', { "favorites" : favorites, "blogs" : blogs, "values" : values, }, context_instance=RequestContext(request) ) enter code here

  • populate a comboBox in Griffon App dynamically

    - by kulkarni
    I have 2 comboBoxes in my View of Griffon App (or groovy swingBuilder) country = comboBox(items:country(), selectedItem: bind(target:model, 'country', value:model.country), actionPerformed: controller.getStates) state = comboBox(items:bind(source:model, sourceProperty:'states'), selectedItem: bind(target:model, 'state', value:model.state)) The getStates() in the controller, populates @Bindable List states = [] in the model based on the country selected. The above code doesn't give any errors, but the states are never populated. I changed the states from being List to a range object(dummy), it gives me an error MissingPropertyException No such property items for class java.swing.JComboBox. Am I missing something here? There are a couple of entries related to this on Nabble but nothing is clear. The above code works if I had a label instead of a second comboBox.

  • Should you do validation checks that go outside the possiblility of normal user activity?

    - by Scarface
    Hey guys I have been thinking about form security a lot lately. I have been told time and time again to check if form input is a number if you are expecting a number or escape it in case (unless you use proper mysqli formatting) to avoid injection. 1.After the safety checks are done, should I do additional logic checks? For example, if the user is sending a friend request to them-self for example even if my user interface will not show the form if the user is looking at their own page.

  • Django models: Use multiple values as a key?

    - by Rosarch
    Here is a simple model: class TakingCourse(models.Model): course = models.ForeignKey(Course) term = models.ForeignKey(Term) Instead of Django creating a default primary key, I would like to use both course and term as the primary key - taken together, they uniquely identify a tuple. Is this allowed by Django? On a related note: I am trying to represent users taking courses in certain terms. Is there a better way to do this? class Course(models.Model): name = models.CharField(max_length=200) requiredFor = models.ManyToManyField(RequirementSubSet, blank=True) offeringSchool = models.ForeignKey(School) def __unicode__(self): return "%s at %s" % (self.name, self.offeringSchool) class MyUser(models.Model): user = models.ForeignKey(User, unique=True) takingReqSets = models.ManyToManyField(RequirementSet, blank=True) takingTerms = models.ManyToManyField(Term, blank=True) takingCourses = models.ManyToManyField(TakingCourse, blank=True) school = models.ForeignKey(School) class TakingCourse(models.Model): course = models.ForeignKey(Course) term = models.ForeignKey(Term) class Term(models.Model): school = models.ForeignKey(School) isPrimaryTerm = models.BooleanField()

  • How to ignore/prevent javadoc folder from validation during Eclipse Build?

    - by h2g2java
    In my war is a huge javadoc folder. There is no point in validating it since javadocs are produced by Sun(Oracle) javadoc utility. I have forgotten how I did it the last time. I need to tell Eclipse build not to validate that particular folder. Reasons why I need it: 1. the html produced by Sun javadoc generation utility does not meet the requirement that Eclipse uses - there is a bug report in Eclipse but Eclipse responds that Sun javadoc generator non-compliance is not their fault and that Eclipse intends to stick to their strict compliance. Which results in lots of html errors listed in the problems tab. 2. the javadoc folder is a remote link and high activity on that link is using up my cpu resource, and because it is a link to a remote location, that cpu high activity is sustained for long time until it finishes scanning the whole 35MB javadocs. Thanks - need help.

  • ASP.NET MVC: Accessing ModelMetadata for items in a collection

    - by DanM
    I'm trying to write an auto-scaffolder for Index views. I'd like to be able to pass in a collection of models or view-models (e.g., IEnumerable<MyViewModel>) and get back an HTML table that uses the DisplayName attribute for the headings (th elements) and Html.Display(propertyName) for the cells (td elements). Each row should correspond to one item in the collection. When I'm only displaying a single record, as in a Details view, I use ViewData.ModelMetadata.Properties to obtain the list of properties for a given model. But what happens when the model I pass to the view is a collection of model or view-model objects and not a model or view-model itself? How do I obtain the ModelMetadata for a particular item in a collection?

  • Conflict between two Javascripts (MailChimp validation etc. scripts & jQuery hSlides.js)

    - by Brian
    I have two scripts running on the same page, one is the jQuery.hSlides.js script http://www.jesuscarrera.info/demos/hslides/ and the other is a custom script that is used for MailChimp list signup integration.

  • Simple form validation. Object-oriented.

    - by kalininew
    Problem statement: It is necessary for me to write a code, whether which before form sending will check all necessary fields are filled. If not all fields are filled, it is necessary to allocate with their red colour and not to send the form. Now the code exists in such kind: function formsubmit(formName, reqFieldArr){ var curForm = new formObj(formName, reqFieldArr); if(curForm.valid) curForm.send(); else curForm.paint(); } function formObj(formName, reqFieldArr){ var filledCount = 0; var fieldArr = new Array(); for(i=reqFieldArr.length-1; i>=0; i--){ fieldArr[i] = new fieldObj(formName, reqFieldArr[i]); if(fieldArr[i].filled == true) filledCount++; } if(filledCount == fieldArr.length) this.valid = true; else this.valid = false; this.paint = function(){ for(i=fieldArr.length-1; i>=0; i--){ if(fieldArr[i].filled == false) fieldArr[i].paintInRed(); else fieldArr[i].unPaintInRed(); } } this.send = function(){ document.forms[formName].submit(); } } function fieldObj(formName, fName){ var curField = document.forms[formName].elements[fName]; if(curField.value != '') this.filled = true; else this.filled = false; this.paintInRed = function(){ curField.addClassName('red'); } this.unPaintInRed = function(){ curField.removeClassName('red'); } } Function is caused in such a way: <input type="button" onClick="formsubmit('orderform', ['name', 'post', 'payer', 'recipient', 'good'])" value="send" /> Now the code works. But I would like to add "dynamism" in it. That it is necessary for me: to keep an initial code essentially, to add listening form fields (only necessary for filling). For example, when the field is allocated by red colour and the user starts it to fill, it should become white. As a matter of fact I need to add listening of events: onChange, blur for the blank fields of the form. As it to make within the limits of an initial code. If all my code - full nonsense, let me know about it. As to me it to change using object-oriented the approach.

  • rails named_scope ignores eager loading

    - by Craig
    Two models (Rails 2.3.8): User; username & disabled properties; User has_one :profile Profile; full_name & hidden properties I am trying to create a named_scope that eliminate the disabled=1 and hidden=1 User-Profiles. The User model is usually used in conjunction with the Profile model, so I attempt to eager-load the Profile model (:include = :profile). I created a named_scope on the User model called 'visible': named_scope :visible, { :joins => "INNER JOIN profiles ON users.id=profiles.user_id", :conditions => ["users.disabled = ? AND profiles.hidden = ?", false, false] } I've noticed that when I use the named_scope in a query, the eager-loading instruction is ignored. Variation 1 - User model only: # UserController @users = User.find(:all) # User's Index view <% for user in @users %> <p><%= user.username %></p> <% end %> # generates a single query: SELECT * FROM `users` Variation 2 - use Profile model in view; lazy load Profile model # UserController @users = User.find(:all) # User's Index view <% for user in @users %> <p><%= user.username %></p> <p><%= user.profile.full_name %></p> <% end %> # generates multiple queries: SELECT * FROM `profiles` WHERE (`profiles`.user_id = 1) ORDER BY full_name ASC LIMIT 1 SHOW FIELDS FROM `profiles` SELECT * FROM `profiles` WHERE (`profiles`.user_id = 2) ORDER BY full_name ASC LIMIT 1 SELECT * FROM `profiles` WHERE (`profiles`.user_id = 3) ORDER BY full_name ASC LIMIT 1 SELECT * FROM `profiles` WHERE (`profiles`.user_id = 4) ORDER BY full_name ASC LIMIT 1 SELECT * FROM `profiles` WHERE (`profiles`.user_id = 5) ORDER BY full_name ASC LIMIT 1 SELECT * FROM `profiles` WHERE (`profiles`.user_id = 6) ORDER BY full_name ASC LIMIT 1 Variation 3 - eager load Profile model # UserController @users = User.find(:all, :include => :profile) #view; no changes # two queries SELECT * FROM `users` SELECT `profiles`.* FROM `profiles` WHERE (`profiles`.user_id IN (1,2,3,4,5,6)) Variation 4 - use name_scope, including eager-loading instruction #UserConroller @users = User.visible(:include => :profile) #view; no changes # generates multiple queries SELECT `users`.* FROM `users` INNER JOIN profiles ON users.id=profiles.user_id WHERE (users.disabled = 0 AND profiles.hidden = 0) SELECT * FROM `profiles` WHERE (`profiles`.user_id = 1) ORDER BY full_name ASC LIMIT 1 SELECT * FROM `profiles` WHERE (`profiles`.user_id = 2) ORDER BY full_name ASC LIMIT 1 SELECT * FROM `profiles` WHERE (`profiles`.user_id = 3) ORDER BY full_name ASC LIMIT 1 SELECT * FROM `profiles` WHERE (`profiles`.user_id = 4) ORDER BY full_name ASC LIMIT 1 Variation 4 does return the correct number of records, but also appears to be ignoring the eager-loading instruction. Is this an issue with cross-model named scopes? Perhaps I'm not using it correctly. Is this sort of situation handled better by Rails 3?

  • how do you reuse a partial view with different ids

    - by oo
    i have a partial view with a dropdown in it. the code looks like this: <%=Html.DropDownListFor(x => Model.Exercises, new SelectList(Model.Exercises, "Id", "Name", Model.SelectedExercise), new { @id = "exerciseDropdown", @class = "autoComplete" })%> the issue is that i want to reuse this partial view in multiple places but i want to have a different id assigned to the control (instead of exerciseDropdown always) but on the outside i only have this . . <% Html.RenderPartial("ExerciseList", Model); %> is there anyway to pass in an id into a partial view. should i stick this into my view model as a seperate property "Model.ExerciseDropdown2" for example. is there a better way ?

  • ASP.NET MVC Page - Viewstate for Confirm email field is getting erased on Registration Page if valid

    - by Rita
    Hi I have a Registaration page with the following fields Email, Confirm Email, Password and Confrim Password. On Register Button click and post the model to the server, the Model validates and if that Email is already Registered, it displays the Validation Error Message "User already Exists. Please Login or Register with a different email ID". While we are displaying this validation error message, I am loosing the value of "Confirm Email" field. So that the user has to reenter again and I want to avoid this. Here I don't have confirm_Email field in my Model. Is there something special that has to be done to remain Confirm Email value on the Page even in case of Validation failure? Appreciate your responses. Here is my Code: <% using (Html.BeginForm()) {%> <%= Html.ValidationSummary(false) %> <fieldset> <div class="cssform"> <p> <%= Html.LabelFor(model => model.Email)%><em>*</em> <%= Html.TextBoxFor(model => model.Email, new { @class = "required email" })%> <%= Html.ValidationMessageFor(model => model.Email)%> </p> <p> <%= Html.Label("Confirm email")%><em>*</em> <%= Html.TextBox("confirm_email")%> <%= Html.ValidationMessage("confirm_email") %> </p> <p> <%= Html.Label("Password")%><em>*</em> <%= Html.Password("Password", null, new { @class = "required" })%> <%= Html.ValidationMessage("Password")%><br /> (Note: Password should be minimum 6 characters) </p> <p> <%= Html.Label("Confirm Password")%><em>*</em> <%= Html.Password("confirm_password")%> <%= Html.ValidationMessage("confirm_password") %> </p><hr /> <p>Note: Confirmation email will be sent to the email address listed above.</p> </fieldset> <% } %>

  • Testing subpackage modules in Python 3

    - by Mitchell Model
    I have been experimenting with various uses of hierarchies like this and the differences between absolute and relative imports, and can't figure out how to do routine things with the package, subpackages, and modules without simply putting everything on sys.path. I have a two-level package hierarchy: MyApp __init__.py Application __init__.py Module1 Module2 ... Domain __init__.py Module1 Module2 ... UI __init__.py Module1 Module2 ... I want to be able to do the following: Run test code in a Module's "if main" when the module imports from other modules in the same directory. Have one or more test code modules in each subpackage that runs unit tests on the modules in the subpackage. Have a set of unit tests that reside in someplace reasonable, but outside the subpackages, either in a sibling package, at the top-level package, or outside the top-level package (though all these might end up doing is running the tests in each subpackage) "Enter" the structure from any of the three subpackage levels, e.g. run code that just uses Domain modules, run code that just uses Application modules, but Application uses code from both Application and Domain modules, and run code from GUI uses code from both GUI and Application; for instance, Application test code would import Application modules but not Domain modules. After developing the bulk of the code without subpackages, continue developing and testing after organizing the modules into this hierarchy. I know how to use relative imports so that external code that puts MyApp on its sys.path can import MyApp, import any subpackages it wants, and import things from their modules, while the modules in each subpackage can import other modules from the same subpackage or from sibling packages. However, the development needs listed above seem incompatible with subpackage structuring -- in other words, I can't have it both ways: a well-structured multi-level package hierarchy used from the outside and also used from within, in particular for testing but also because modules from one design level (in particular the UI) should not import modules from a design level below the next one down. Sorry for the long essay, but I think it fairly represents the struggles a lot of people have been having adopting to the new relative import mechanisms.

  • How do I run jQuery form validation by class?

    - by joshcomley
    Hi there, I've been using the jQuery form validator, but I can't seem to figure out how to trigger it by class. Take this example: $("#myform").validate({ rules: { field: { required: true, date: true } } }); Where field it is expecting the name of the particular input. But, what if I have the following: <input class="date".... /> How can I tell the validator to validate all inputs with a "date" class as a date?

  • How to avoid piracy in iPhone apps by server side validation?

    - by prathumca
    As par my app requirement, there is a couple of scenarios that I need to handle. Scenario 1: To avoid piracy, I want to include some piece of code, whose job is sending both IMEI and Serial number of IPhone. Scenario 2: At server side, I've a database, which has a list of both IMEI and Serial No info. Here I wanna validate both IMEI and Serial numbers. If both are not matched then I can make sure that the app is pirated. Idea seems good. But I don't know how to handle these two scenarios in my app. Any help is greatly appreciated.
