uuid

问题 When I do manage.py syncdb I get: Error: One or more models did not validate: users.userprofile: "uuid": Primary key fields cannot have null=True. even though my class UserProfile(models.Model) have: uuid = UUIDField(primary_key=True, auto=True, editable=False) 回答1: The comment from Daniel was probably it, I just didn't know how to follow the clue. The fix, that came from Joshua, was to remove the official django-uuidfield 's and replace them with Joshua's fork. -django-uuidfield==0.4 -django

问题 Check this, List<String> list = new ArrayList<String>(); for (int i = 0; i < 10000; i++) { String value = (""+UUID.randomUUID().getLeastSignificantBits()).substring(3, 20); assertFalse(list.contains(value)); assertTrue(value.length() < 18); list.add(value); } This method is passing like charm. And I am in the impression that it is slightly better to take least significant bits, rather than the most significant. Because in the most significant bits you have 6 bits fixed for some info, and with

问题 I know this question has been asked here: GraphAware Neo4j UUID not working. Nobody has answered it and I cant comment to ask that guy because I dont have enough reputation. I have all both the server framework and the uuid jar files in plugins folder and this is my config: com.graphaware.runtime.enabled=true com.graphaware.module.UIDM.1=com.graphaware.module.uuid.UuidBootstrapper com.graphaware.module.UIDM.uuidProperty=uuid For some reason when I create a node. I'm not getting anything. This

问题 I am trying to make an application that transfers Strings of data from my Android phone to my Laptop running Windows 7 (and Vice-Versa) over Bluetooth. I figured that I would open up a Server-Socket on the Windows Machine and program the Android app to start a Client-Socket. But being aware that Android SDP(Service Discovery Protocol) and connects By a UUID, created a point where in I am confused. Confused on how I should start up a server socket on the Server Side Using the Windows API. MY

问题 Here is my problem: My server crashed last night! So i had to go out and buy some new stuff and i now have a new server. I have everything set back up and i am trying to set my svn server back up. I have it set back up. I have my files on another pc that i want to commit to the svn server to start my repository back up. How do i get those files into the repository again? The server has the same ip as it was before. I have tried a relocate and a switch, but i keep getting this error: The

问题 I want to use SolrJ for indexing a set of Java classes. Each class instance is determined by its id which is unique within a class. However, by using the Solr @Field annotation for making Solr documents from these classes it turns out that this annotation doesn't guarantee uniqueness of the created documents stored in the Solr index (same id values may belong to multiple classes). I tried combining the annotation approach with the Solr UUID data type for generating unique id values into a

问题 Is there a way to convert a UUID to a UUID5 in an existing postgres data set? I have a master/slave setup with pglogical replicating specific tables & columns. I need to give access to this replicated data to a third party, but I want to anonymise it as much as possible. Every row in a table uses a UUID (generated in code) as primary key, but in order to ensure anonymity I need to ensure that the primary keys of the master & replicated tables are one-way transformed to make back-tracing

问题 In the simulator, I don't have this problem but when I run the app on my device applicationDidBecomeActive and applicationWillTerminate aren't called. Is it because I'm jailbroken and running backgrounder etc?
