migration

问题 im new to entity framework , i created my entities from reverse engineering from a Mysql database that i have created in mysqlworkbench , and then i added some foreign keys in my entities and then i added a migration and tried to update my database but an error occured and it indicates that: "Table 'pidev.pidev.personal' doesn't exist".

问题 I'm trying to convert an ant build file to Gradle and I was wondering if there exists a way to specify which packages should be in the javadoc in the same way 'packagenames' works in ant? Thanks Jonathan 回答1: See the 'includes'/'excludes' properties, or related methods. The patterns use the same syntax as ant. javadoc { exclude "**/internal/**" } As another example, if the build process generates Java source files into a build directory, the Javadocs can be generated using: javadoc { source =

问题 How to correctly drop and then recreate ENUM type with sequelize for Postgres in migrations? For example this migration doesn't drop enum_Users_status enum... so any attempts to recreate/change status values after they have been once created fail. module.exports = { up: function (queryInterface, DataTypes) { queryInterface.createTable('Users', { //... status: { type: DataTypes.ENUM, values: [ 'online', 'offline', ], defaultValue: 'online' } //... }) }, down: function (queryInterface) {

问题 I'm working on upgrading a legacy project, currently still on Python 2.7.18 as the highest Python-2 before upgrade to 3. After upgrading Django from 1.8.13 to 1.11.29, the project requires some database changes (unapplied migrations), and I'm using command python manage.py sqlmigrate to review the SQL statements. I have some questions, and any inputs will be highly appreciated: Some migrations, e.g. 0002_logentry_remove_auto_add below, SQL only contains comment, I'm wondering why. (venv)

问题 I would like to create a new namespace which is identical to the old one. My approach would look something like this (full command below): kubectl get <resources> -o json --namespace OLD-NAMESPACE | jq '.items[].metadata.namespace = "NEW-NAMESPACE"' | kubectl create -f - This basically gets all resource definitions in a json format, replaces the old namespace with the new one, and applies everything. Unfortunately, this does not work, since the old definitions contain namespace specific
