Cannot bind source type Umbraco.Web.Models.PartialViewMacroModel

I am trying to create a macro so that I can easily insert my ContactForm.cshtml partial page anywhere in a content section.

No matter how much I try the result is usually the same, either I get stuck with the page displaying "Macro alias: InsertContactForm" where the partial page should render.

I am using a seperate webservice to process the request, so I have javascript that validates and sends the information. I am not using a controller or model.

I see this error:

 Error loading Partial View (file: ~/Views/MacroPartials/InsertContactForm.cshtml). Exception: Umbraco.Web.Mvc.ModelBindingException: Cannot bind source type Umbraco.Web.Models.PartialViewMacroModel to model type Umbraco.Web.Models.RenderModel.

My InsertContactForm.cshtml (under macro partials)

        @inherits Umbraco.Web.Macros.PartialViewMacroPage

        @Html.Partial("ContactForm")

My ContactForm.cshtml (under partials) if it helps

@inherits Umbraco.Web.Mvc.UmbracoTemplatePage

    <form id="contact" role="form" class="" data-submit="" method="POST">
          @Html.AntiForgeryToken()
            <div class="form-group">
                    <label class="control-label">Name</label>

                </div>

I am still learning, perhaps macro's are not meant to be used this way. Regardless I figured that the point of a macro was to be reusable, and in this case the contact form is not intended to be reused.

So what I did instead was delete the macro stuff and simply created a template and added it to the optional templates on my landing page document type and selected the new template for use on that specific page. In the template I included an Html.Partial which added my partial .cshtml page to the end of the document.

A late reply, but hopefully helpful for anyone else who experiences this problem.

Instead of using @inherits Umbraco.Web.Mvc.UmbracoTemplatePage, as this is what's causing the conflict between this and Umbraco.Web.Models.PartialViewMacroModel

If you leave out the 'inherits' bit all together, you can initialise

var umbracoHelper = new Umbraco.Web.UmbracoHelper(Umbraco.Web.UmbracoContext.Current);

and call

umbracoHelper.TypedContent(xxxx) instead of Umbraco.TypedContent(xxxx) ... for instance

umbracoHelper gives you access to all the same functionality as you get by inheriting the model through @inherits
