python - Django 迁移未应用于连接的数据库

Question

因此，我正在努力调整现有的 django (v1.11.5) 项目，并迁移了我的修改:

$ python2 manage.py makemigrations
Migrations for 'genetics_ark':
  genetics_ark/migrations/0002_analysis_analysisvariant_annotation_cnv_decon_deconcnv_decongene_decongenecnv_deconsample_gene_genep.py
    - Create model Analysis
    - Create model AnalysisVariant
    - Create model Annotation
    - Create model Gene
    - Create model GenePanel
    - Create model Meta
    - Create model Model
    - Create model ModelRegion
    - Create model Panel
    - Create model Reference
    - Create model Region
    - Create model SamplePanel
    - Create model Transcript
    - Create model TranscriptRegion
    - Create model CNV
    - Create model Decon
    - Create model DeconCNV
    - Create model Decongene
    - Create model DecongeneCNV
    - Create model DeconSample

$ python2 manage.py migrate
System check identified some issues:

但是，我添加的模型没有添加到数据库中，而 django 部分是:

• auth_group
• auth_group_permissions
• auth_permission
• auth_user
• auth_user_groups
• auth_user_user_permissions
• django_admin_log
• django_content_type
• django_migrations
• django_session

我已经使用该项目的早期版本修改了数据库，但我找不到任何可以解释它不起作用的差异。此外，当我“runserver”时，它不起作用，并且终端中不会显示错误消息。有什么建议吗？

尝试

python2 manage.py makemigrations <app_name>

Django 在初始阶段没有检测到迁移的变化..所以你必须第一次指定应用程序名称..之后你可以简单地这样做

python2 manage.py makemigrations
