  • Removing quotation marks in JSONObject

    - by Spike Williams
    I'm using the net.sf.json.JSONObject to create some data to be sent to a front end application, and I don't like the ways ts adding quotation marks to every field name. For example: myString = new JSONObject().put("JSON", "Hello, World!").toString(); produces the string {"JSON": "Hello, World"}. What I want it to return is {JSON: "Hello, World"} - without quotes around "JSON". What do I have to do to make that happen?

  • Django form and User data

    - by Dean
    I have a model that looks like this: class Client(models.Model): name = models.CharField(max_length=100, primary_key=True) user = models.ForeignKey(User) class Contract(models.Model): title = models.CharField(max_length=100, primary_key=True) start_date = models.DateField() end_date = models.DateField() description = models.TextField() client = models.ForeignKey(Client) user = models.ForeignKey(User) How can i configure a django form so that only clients associated with that user show in the field in the form? My initial thought was this in my forms.py: client = forms.ModelChoiceField(queryset=Client.objects.filter(user__username = User.username)) But it didn't work. So how else would I go about it?

  • Copy only files that are newer

    - by ErocM
    I am currently using this code: if (!Directory.Exists(command2)) Directory.CreateDirectory(command2); if (Directory.Exists(vmdaydir)) Directory.Delete(vmdaydir,true); if (!Directory.Exists(vmdaydir)) Directory.CreateDirectory(vmdaydir); var dir = Path.GetDirectoryName(args[0]); sb.AppendLine("Backing Up VM: " + DateTime.Now.ToString(CultureInfo.InvariantCulture)); Microsoft.VisualBasic.FileIO.FileSystem.CopyDirectory(dir, vmdaydir); sb.AppendLine("VM Backed Up: " + DateTime.Now.ToString(CultureInfo.InvariantCulture)); As you can see, I am deleting the directory, then I am copying the folder back. This is taking way to long since the directory is ~80gb in size. I realized that I do not need to copy all the files, only the ones that have changed. How would I copy the files from one folder to another but only copying the files that are newer? Anyone have any suggestions? ==== edit ==== I assume I can just do a file compare of each file and then copy it to the new directory, iterating through each folder/file? Is there a simpler way to do this?

  • Validating using stripes causes bound values to delete

    - by Davoink
    I'm using Stripes and I am validating the values of a drop down box to ensure the user selects an option. On initial load all data is present, but once the validation kicks in the form loses the data that was set up in the action bean on load. This includes the original list I am validating against. I'm simply using in the jsp, and annotating the field in the action bean as @Validate(required=true). Am I missing something simple? Cheers

  • How to handle very frequent updates to a Lucene index

    - by fsm
    I am trying to prototype an indexing/search application which uses very volatile indexing data sources (forums, social networks etc), here are some of the performance requirements, Very fast turn-around time (by this I mean that any new data (such as a new message on a forum) should be available in the search results very soon (less than a minute)) I need to discard old documents on a fairly regular basis to ensure that the search results are not dated. Last but not least, the search application needs to be responsive. (latency on the order of 100 milliseconds, and should support at least 10 qps) All of the requirements I have currently can be met w/o using Lucene (and that would let me satisfy all 1,2 and 3), but I am anticipating other requirements in the future (like search relevance etc) which Lucene makes easier to implement. However, since Lucene is designed for use cases far more complex than the one I'm currently working on, I'm having a hard time satisfying my performance requirements. Here are some questions, a. I read that the optimize() method in the IndexWriter class is expensive, and should not be used by applications that do frequent updates, what are the alternatives? b. In order to do incremental updates, I need to keep committing new data, and also keep refreshing the index reader to make sure it has the new data available. These are going to affect 1 and 3 above. Should I try duplicate indices? What are some common approaches to solving this problem? c. I know that Lucene provides a delete method, which lets you delete all documents that match a certain query, in my case, I need to delete all documents which are older than a certain age, now one option is to add a date field to every document and use that to delete documents later. Is it possible to do range queries on document ids (I can create my own id field since I think that the one created by lucene keeps changing) to delete documents? Is it any faster than comparing dates represented as strings? I know these are very open questions, so I am not looking for a detailed answer, I will try to treat all of your answers as suggestions and use them to inform my design. Thanks! Please let me know if you need any other information.

  • How would you structure your entity model for storing arbitrary key/value data with different data t

    - by Nathan Ridley
    I keep coming across scenarios where it will be useful to store a set of arbitrary data in a table using a per-row key/value model, rather than a rigid column/field model. The problem is, I want to store the values with their correct data type rather than converting everything to a string. This means I have to choose either a single table with multiple nullable columns, one for each data type, or a set of value tables, one for each data type. I'm also unsure as to whether I should use full third normal form and separate the keys into a separate table, referencing them via a foreign key from the value table(s), or if it would be better to keep things simple and store the string keys in the value table(s) and accept the duplication of strings. Old/bad: This solution makes adding additional values a pain in a fluid environment because the table needs to be modified regularly. MyTable ============================ ID Key1 Key2 Key3 int int string date ---------------------------- 1 Value1 Value2 Value3 2 Value4 Value5 Value6 Single Table Solution This solution allows simplicity via a single table. The querying code still needs to check for nulls to determine which data type the field is storing. A check constraint is probably also required to ensure only one of the value fields contains non-nulll data. DataValues ============================================================= ID RecordID Key IntValue StringValue DateValue int int string int string date ------------------------------------------------------------- 1 1 Key1 Value1 NULL NULL 2 1 Key2 NULL Value2 NULL 3 1 Key3 NULL NULL Value3 4 2 Key1 Value4 NULL NULL 5 2 Key2 NULL Value5 NULL 6 2 Key3 NULL NULL Value6 Multiple-Table Solution This solution allows for more concise purposing of each table, though the code needs to know the data type in advance as it needs to query a different table for each data type. Indexing is probably simpler and more efficient because there are less columns that need indexing. IntegerValues =============================== ID RecordID Key Value int int string int ------------------------------- 1 1 Key1 Value1 2 2 Key1 Value4 StringValues =============================== ID RecordID Key Value int int string string ------------------------------- 1 1 Key2 Value2 2 2 Key2 Value5 DateValues =============================== ID RecordID Key Value int int string date ------------------------------- 1 1 Key3 Value3 2 2 Key3 Value6 How do you approach this problem? Which solution is better? Also, should the key column be separated into a separate table and referenced via a foreign key or be should it be kept in the value table and bulk updated if for some reason the key name changes?
