How to track which seeders got applied in Laravel?

由 送分小仙女□ 提交于 2019-12-11 16:10:15
问题 The obvious way to apply specific seeds rather than seeding everything is by using the --class flag: php artisan db:seed --class[=CLASS] Is there a way to track which seeders have been applied so far in Laravel (say, the same way you can track how migrations got applied by running php artisan migrate:status )? Further, is there a way to apply a range of seeders (rather than specifying each class individually, which is very cumbersome). What made me think about this is this part in a seeder in

Why do I get different results with same random seed, same computer, same program

由 纵然是瞬间 提交于 2019-12-10 11:42:51
问题 I am running a simulation with a lot of modules. I use random a number of times. I read input files. I use rounding. Of course, I am setting a random.seed(1) in the very first line of my program, immediately after importing random. Even though, shouldn't I get exactly the same result running the same program same parameters in the same computer with the same input files? 回答1: Inject the source for random numbers as a service into the modules using it. You can then easily replace it with a

Using Paperclip within seeds.rb

由 会有一股神秘感。 提交于 2019-12-09 08:07:12
问题 Let's says I have the following entry in my seeds.rb file : Image.create(:id => 52, :asset_file_name => "somefile.jpg", :asset_file_size => 101668, :asset_content_type => "image/jpeg", :product_id => 52) If I seed it, it tries to process the image specified, I get this error : No such file or directory - {file path} etc... My images are backed up, so I don't really need to create them; but I need the record though. I can't comment the paperclip directive in my model; then it works; but I

Independent instances of 'random'

由 假装没事ソ 提交于 2019-12-08 14:56:33
问题 The below code attempts to illustrate what I want. I basically want two instances of "random" that operate independently of each other. I want to seed "random" within one class without affecting "random" in another class. How can I do that? class RandomSeeded: def __init__(self, seed): import random as r1 self.random = r1 self.random.seed(seed) def get(self): print self.random.choice([4,5,6,7,8,9,2,3,4,5,6,7,]) class Random: def __init__(self): import random as r2 self.random = r2 self.random

Seed data for grails application

由 十年热恋 提交于 2019-12-08 03:04:32
问题 What is the best way to load seed (initial or test) data into grails application. I'm considering 3 options Putting everything in *BootStrap.groovy files. This is tedious if the domain classes and test data are many. Write custom functionality to load it through xml. May not be too difficult with the excellent xml support by groovy, but lot of switch statements for different domain classes. Use Liquibase LoadData api. I see you can load the data fairly easy from csv files. Choice 3 seems the

How to set MessageDigest seed?

由 ぐ巨炮叔叔 提交于 2019-12-08 02:37:45
问题 The MessageDigest class implements the SHA-1 algorithm (among many others). The SHA-1 algorithm allows one to use different "seeds" or initial digests. See SHA-1 Psuedocode The algorithm initializes variables, or the seed: Initialize variables: h0 = 0x67452301 h1 = 0xEFCDAB89 h2 = 0x98BADCFE h3 = 0x10325476 h4 = 0xC3D2E1F0 However the MessageDigest class, as described in the Online Java Manual, provides no API for setting these initial variables. In fact, it doesn't state the value of the

Why is Bash’s $RANDOM not seeded (?) on some machines?

由 為{幸葍}努か 提交于 2019-12-07 05:17:47
问题 I noticed that on some machines (all openSUSE 11.2 on identical hardware) every Bash shell would output the same sequence of values for $RANDOM : $ bash -c 'for i in `seq 10`; do echo -n "$RANDOM "; done; echo' 17767 9158 6249 18547 23633 23807 5194 22764 7977 31949 $ bash -c 'for i in `seq 10`; do echo -n "$RANDOM "; done; echo' 17767 9158 6249 18547 23633 23807 5194 22764 7977 31949 The sequence is the same across all these machines. It seems that the random number generator is not seeded?
