nyz-dynamic-design-builder 2.0.1

Dynamic Excel export builder for Django ORM querysets

🧩 nyz-dynamic-design-builder

nyz-dynamic-design-builder is a lightweight Django-compatible Python utility for exporting model data — including ForeignKey and ManyToMany fields — into a structured pandas.DataFrame format. You can write it to Excel if needed.

No serializers or admin customization required. Just your model and your queryset.

---

📦 Installation

pip install nyz-dynamic-design-builder

---

📝 Sample Model: Blog

from django.db import models
from django.contrib.auth import get_user_model

User = get_user_model()

class Tag(models.Model):
    name = models.CharField(max_length=100)

class Blog(models.Model):
    title = models.CharField(max_length=255)
    content = models.TextField()
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    tags = models.ManyToManyField(Tag, blank=True)
    created_at = models.DateTimeField(auto_now_add=True)

---

⚙️ Usage

from nyz_dynamic_design_builder.exporter import export_data

queryset = Blog.objects.all()

df = export_data(
    query=queryset,
    field_list=["title", "content", "author", "tags", "created_at"],
    search_fk_list=["text", "name", "username", "first_name", "last_name"],
    special_fk_values={
        "author": ["username", "first_name", "last_name", "is_active"]
    },
    special_m2m_fields={
        "tags": ["name"]
    },
    ignore_m2m_fields=["id", "created_at", "updated_at"]
)

df.to_excel("blog_export.xlsx", index=False)

🔍 Parameters Explained

Parameter	Description
query	Django queryset (e.g. Blog.objects.all())
field_list	Fields to export from the model (including FK/M2M)
search_fk_list	List of attributes to try in FK fields (fallback order)
special_fk_values	Dict: FK field -> list of subfields to extract
special_m2m_fields	Dict: M2M field -> list of subfields to extract
ignore_m2m_fields	M2M fields or subfields to ignore

---

🧠 How It Works

• For ForeignKey fields:

  • If listed in special_fk_values, it exports the specified subfields.
  • Else, it searches through search_fk_list and uses the first match.

• For ManyToMany fields:

  • If listed in special_m2m_fields, only those subfields are exported.
  • Otherwise, all subfields are exported except those in ignore_m2m_fields.

---

📤 Output Example

Columns in the Excel might look like:

• Title
• Content
• Author - Username
• Author - First Name
• Author - Last Name
• Author - Is Active
• Tags 1 - Name
• Tags 2 - Name
• Created At

---

✅ Perfect For

• Admin-level or reporting exports
• Human-readable outputs for nested fields
• Avoiding verbose serializers or views for temporary data output
• Excel generation from any model dynamically

---

🔒 Notes

• You control exactly which fields and subfields are included.
• pandas and openpyxl are required.
• You can use .to_excel(), .to_csv() or any other pandas method after export.
