Partials 部分

This document only applies when using https://github.com/gobuffalo/buffalo/tree/main/render.

​ 仅当使用 https://github.com/go/tree/main/render 时，此文档才适用。

Please see github.com/gobuffalo/plush for more details on the underlying templating package.

​ 有关基础模板包的详细信息，请参阅 github.com/go/plush。

Usage 用法

You can call your partials using partial plush helper:

​ 您可以使用 partial plush 帮助器调用您的部分：

templates/users/form.plush.html

templates/users/new.plush.html

Output 输出

1
2
3

<form action="/users/" method="POST">
<!-- form content here  -->
<form>

Context 上下文

All rendering context from the parent template will automatically pass through to the partial, and any partials that partial may call. (see also Context)

​ 父模板的所有渲染上下文将自动传递到部分，以及该部分可能调用的任何部分。（另请参阅上下文）

actions/users.go

templates/users/edit.plush.html

templates/users/form.plush.html

Output 输出

1
2
3
4
5

func UsersEdit(c buffalo.Context) error {
	user := User{
		Name: "John Smith",
	}
	// ...
	c.Set("user", user)
	return c.Render(http.StatusOK, render.HTML("users/edit.plush.html"))
}

Local Context 局部上下文

In addition to have the global context, you can set additional variable only for partials as “local” variables.

​ 除了拥有全局上下文外，您还可以仅为局部变量设置其他变量，作为“局部”变量。

actions/colors.go

templates/colors/index.plush.html

templates/colors/details.plush.html

Output 输出

 1
 2
 3

func ColorsHandler(c buffalo.Context) error {
  colors := map[string]interface{}{
		"White":  "#FFFFFF",
		"Maroon": "#800000",
		"Red":    "#FF0000",
		"Purple": "#800080",
	}

	c.Set("colors", colors)
	return c.Render(http.StatusOK, r.HTML("colors/index.plush.html"))
}

Helpers 帮助程序

Partials are not much different from standard templates in Buffalo. They include all of the same helpers as well.

​ 局部模板与 Buffalo 中的标准模板没有太大区别。它们也包含所有相同的帮助程序。
