model

问题 My question is how to get metadata besides totalRecords, in my case it is version, code, searchquery (please look at json). { "result": { "version":"1", "code":"200", "searchquery": "false", "totalRecords": "2", "account":[ { "lastname": "Ivanoff", "firstname": "Ivan", "accountId":"1" }, { "lastname": "Smirnoff", "firstname": "Ivan", "accountId":"2" } ] } } Here is my model: Ext.define("test.Account", { extend: "Ext.data.Model", fields: [ {name: 'accountId', type: 'string'}, {name: 'lastname'

问题 QCompleter works slightly slow on large data sets (large models): when I start to input characters in QCombobox it passes few seconds to show auto-complete popup with variants, when input 2nd char QCompleter does not react on key press for few seconds as well. Next characters works fine. Model size is about 100K records. Is it possible to improve QCompleter performance or show popup after 2nd or 3rd input symbol? Are there some good examples? 回答1: Solution appears similar to this: https:/

问题 I'm trying to figure out the best way to load a textured 3D model into my webGL application but I'm having some trouble with it. My 3D models have more than 1 texture and I don't know how to tell the shader which texture to use per vertex as this info doesn't seem to be included into the 3D files I looked into so far. I'll give an example: I have modeled a wooden chair with a leather seat/cushion in Blender. Which format should I export the chair to make it easy and efficient to extract: -

问题 So I'm trying to work this out last night, and after thinking myself around in circles a few times decided I need some help. I did post a question about an ID field not being filled in but it got too long winded and confusing, and I realised the problem was probably based on the associations. I'm working on a customer database. For larger business customers the relationships get a little complicated. I have 3 models, Customer, CustomerAddress and CustomerContact. A customer can have many

问题 I have three tables: Member MemberBranch Branch The Member can have many Branch es through MemberBranch . And a Branch can have many Member s etc. What I want to be able to do is get a count of how many members a branch has. so $branch = Branch::find_by_title('London'); $branch->number_of_members; // Will equal how many members have the branch through MemberBranch How would I go about doing this? 回答1: Try this: SELECT B.*, (SELECT count(*) as total from MembersBranch where branch_id = B.id)

问题 I'm using the Telerik PanelBar to do some asynchronous loading using a partial view. I'm creating a model for the partial view in a parent view, but for some reason my data isn't coming through in tact. // Parent view <% Html.Telerik().PanelBar().Name("PanelBar").HtmlAttributes(new { style = "padding-left: 0em;" }).Items(items => { foreach (var item in Model.Visits) { SiteVisitDetailModel model = new SiteVisitDetailModel(); model.URL = item.Key; // this is properly set model.Dates = new List

问题 I've exported a model from blender but I want some instances to use a different texture if (x % 2 == 0) { shipInstance.materials.clear(); shipInstance.materials.add(new Material()); shipInstance.materials.get(0).set(new TextureAttribute(TextureAttribute.Diffuse, enemyTexture)); unfortunately doesn't work! In a similar way I want to be able to change things like shininess and smoothing (I'm guessing you can change things like this that are using the default shader?) I've also (later) tried

问题 I have an issue with updating my webgrid with a new model which is returned from my DAL. On my view I have checkboxes used to filter data displayed on the grid. Once a checkbox is ticked this calls some jQuery ajax function which passes the checkbox values to my method in my controller. This then calls my DAL and it returns a new list of my model with the correct values. I return this list to my view but when the page loads nothing is different. The grid looks the same which isn't what I

问题 In suppliment to this question, if business logic should be in the model, how do I return an error message from the model? def save(self, *args, **kwargs): if <some condition>: #return some error message to the view or template 回答1: Pastylegs is correct, but you shouldn't be doing that sort of logic in the save method. Django has a built-in system for validating model instances before saving - you should use this, and raise ValidationError where necessary. 回答2: Raising an exception is the way
