The RecursiveCharacterTextSplitter, LatexTextSplitter, and PythonCodeTextSplitter textsplitters are not being used in the application. They have been commented out to improve code readability and reduce clutter.
This commit removes unused files and imports from the template directory. The deleted files are base.py, fields.py, and nodes.py. The deleted imports are from langflow.template.constants. This improves the codebase by removing unnecessary code and reducing clutter.
✨ feat(frontend_node): add constants module
This commit adds a new module called constants to the frontend_node directory. The module contains constants used in the frontend_node module. The constants are FORCE_SHOW_FIELDS, DEFAULT_PROMPT, SYSTEM_PROMPT, and HUMAN_PROMPT. This improves the codebase by centralizing the constants in one module.
🐛 fix(frontend_node): use ast.literal_eval instead of eval
This commit fixes a security vulnerability by replacing the use of eval with ast.literal_eval in the UtilitiesFrontendNode class. The method converts a string representation of a list to an actual list. The use of eval is dangerous as it can execute arbitrary code. This improves the codebase by making it more secure.
🔨 refactor(util.py): add format_instructions to the list of fields to format in format_dict function
The suffix and format_instructions fields in the ZeroShotPromptNode class were swapped to improve the readability of the code. The format_instructions field is now above the suffix field, which makes more sense as it is a required field. In the util.py file, the format_instructions field was added to the list of fields to format in the format_dict function. This ensures that the format_instructions field is properly formatted when the function is called.
✨ feat(template): add method to add fields to a template
The VectorStoreFrontendNode now supports adding extra fields to its template. The add_extra_fields method is called after the node is loaded and adds the weaviate_url field to the template if the node is of type Weaviate. The Template class now has a method to add fields to a template. This method is used by the VectorStoreFrontendNode to add the weaviate_url field to its template.
Added new text splitters to the configuration file: RecursiveCharacterTextSplitter, LatexTextSplitter, and PythonCodeTextSplitter. These text splitters will be used to split text into smaller chunks for processing. Also, added new toolkits to the configuration file: OpenAPIToolkit and JsonToolkit. These toolkits will be used to process the text chunks generated by the text splitters.
The CohereEmbeddings is added to the list of supported embeddings in the config.yaml file. This allows the application to use the CohereEmbeddings for language processing tasks.
✨ feat(pyproject.toml): add cohere dependency to enable new features
🔧 chore(config.yaml): add Cohere to the list of supported LLMS
The langchain dependency was updated to version 0.0.183 to take advantage of the latest features and bug fixes. The cohere dependency was added to enable new features. Cohere is now added to the list of supported LLMS in the config.yaml file.
The try_setting_streaming_options function now correctly sets the streaming attribute of the llm object to True if it is an instance of BaseLanguageModel and has the streaming attribute. This fixes a bug where the streaming attribute was not being set correctly.
🐛 fix(utils.py): fix setting of streaming option for llm
🎨 style(llms.py): add model_file and model_type fields to the list of non-advanced fields
The first change adds CTransformers to the list of supported llms in the config.yaml file. The second change fixes a bug in the try_setting_streaming_options function in utils.py where the streaming option was not being set correctly. The third change is a style change that adds the model_file and model_type fields to the list of non-advanced fields in the LLMFrontendNode class in llms.py.
✅ test(embeddings_template.py): add tests for openai fields formatting
The openai fields formatting is now done in a separate method, which improves the readability and maintainability of the code. Tests were added to ensure that the formatting is done correctly.
The previous condition was checking if the content was None, but it should check if it is empty. This change fixes the error message to be more accurate.
The prompt field was previously set as not required when no value was provided, but this is not the intended behavior. The prompt field should always be required, even if the default prompt is used. This commit fixes the issue by setting the required attribute to True when the value is None.
The `format_openai_field` method formats the display name of fields that contain the string "openai" in their name. It capitalizes the first letter of "OpenAI", replaces underscores with spaces, and replaces "Api" with "API". This improves the readability and consistency of the display names of OpenAI fields.
🚀 feat(config.yaml): add HuggingFaceEmbeddings to embeddings
The Jina and sentence-transformers dependencies were added to the project to improve the functionality of the application. The HuggingFaceEmbeddings was added to the embeddings in the config.yaml file to improve the quality of the embeddings used in the application.
Issue #375, #372
The filter parameter name was ambiguous and could be interpreted in different ways. Renaming it to filter_messages makes it clear that it is used to filter chat messages.
🔥 refactor(custom.py): remove unused import of SQL_FORMAT_INSTRUCTIONS
🔥 refactor(custom_lists.py): remove unused import of SQLDatabase and utility_type_to_cls_dict
🔥 refactor(utilities/base.py): remove unused import of utility_type_to_cls_dict
🔥 refactor(utils/util.py): remove unused function build_template_from_parameters
The changes made are mostly removing unused imports and renaming a parameter for clarity. The import of SQL_FORMAT_INSTRUCTIONS was removed as it was not being used. The function build_template_from_parameters was removed as it was not being used.
✨ feat(base.py): add support for SQLDatabase utility and filter utilities according to settings.utilities
🎨 style(frontend_node/base.py): add display_name to fields
🎨 style(frontend_node/utilities.py): format field values and types
The import statement for UtilitiesFrontendNode was incorrect, causing an import error. The import statement was corrected to import from the correct module.
Support for SQLDatabase utility was added to the type_to_loader_dict dictionary. The dictionary is now filtered according to the settings.utilities list.
The display_name attribute was added to fields in the FrontendNode class to improve the readability of the frontend.
The format_field method in the UtilitiesFrontendNode class was updated to format field values and types. The method now converts field.field_type to a list if it is a Literal type and formats field.value if it is a dictionary.
The description of the SQLAgentNode has been updated to reflect its new implementation, which now constructs a SQL agent from an LLM and tools instead of a Vector Store Router. This change was made to improve the accuracy of the description and to better reflect the functionality of the node.
🔥 refactor(custom_lists.py): remove unused import of vectorstores
The import of deepcopy in nodes.py and vectorstores in custom_lists.py are not used in the codebase and can be safely removed to improve code readability and maintainability.
Weaviate has been added to the list of vectorstores in the config.yaml file. A TODO comment has been added to the nodes.py file to fix the integration with Weaviate. Weaviate requires the weaviate_url to be passed as it is not part of the class or from_texts method. The add_extra_fields method needs to be fixed to include the weaviate_url parameter.
This commit extracts common field attributes to variables and sets them accordingly. The basic_fields and advanced_fields variables are used to set the show and advanced attributes of the fields. The API Key field is now displayed as "API Key" and its value is hidden. The location field now has a default value of ":memory:" and its placeholder is also set to ":memory:". The password attribute of the key fields is set to False.
Issue Implement Qdrant #361
🐛 fix(langflow): remove unused imports in base.py files
The variable node in LangChainTypeCreator was causing a type error, so a type ignore was added to fix the issue. Additionally, unused imports were removed from both base.py files.
The process_field method in the TemplateFieldCreator class is not used anywhere in the codebase and is therefore removed to improve code readability and maintainability.
This commit refactors the FrontendNode.format_field() method to improve its readability and maintainability. The method now uses helper methods to handle specific field types and values, and to determine whether a field should be shown, be a password field, or be multiline. The method also uses a dictionary to handle special fields and their respective handlers.
✨ feat(config.yaml): add Qdrant vectorstore and RequestsWrapper to the config.yaml file
The config.yaml file has been updated with new documentloaders, memories, prompts, textsplitters, toolkits, utilities, and vectorstores. The Qdrant vectorstore has been added to the vectorstores section. The RequestsWrapper has been added to the wrappers section.
🐛 fix(nodes.py): remove deepcopying of certain objects to improve performance
🐛 fix(loading.py): add error handling for empty documents in instantiate_textsplitter
The is_first_message logic in chat_manager.py was not correctly identifying the first message. The fix in this commit changes the comparison to <= 1 instead of == 0. In nodes.py, deepcopying of certain objects was removed to improve performance. This was done because deepcopying was not necessary for these objects. In loading.py, error handling was added to handle empty documents in instantiate_textsplitter. This was done to prevent errors when the source provided did not load correctly or was empty.
✨ feat(__main__.py): add serve_on_jcloud function to deploy Langflow server on Jina AI Cloud
🐛 fix(config.yaml): remove duplicate entries and fix indentation
The update_settings function now accepts a dev flag to enable running the app in development mode. The serve_on_jcloud function has been added to deploy the Langflow server on Jina AI Cloud. The config.yaml file has been cleaned up by removing duplicate entries and fixing indentation.
🔨 refactor(vector_store/base.py): refactor VectorstoreCreator to use import_class from langflow.interface.importing.utils
The `vectorstores_type_to_cls_dict` variable was not being used, so it was removed. The `VectorstoreCreator` class was refactored to use the `import_class` function from `langflow.interface.importing.utils` instead of importing it directly. This improves the code's readability and maintainability.
🐛 fix(base.py): correctly handle nested lists in Node.build() method
✨ feat(vector_store): add VectorStoreFrontendNode to handle vector store templates
🐛 fix(util.py): add build_template_from_method to correctly build templates from class methods
The configuration file now includes two new vector stores, DocArrayHnswSearch and DocArrayInMemorySearch. The Node.build() method now correctly handles nested lists. A new VectorStoreFrontendNode has been added to handle vector store templates. The build_template_from_method function has been added to correctly build templates from class methods.
Issue #335
The import statements for pathlib.Path and fastapi.staticfiles.StaticFiles were not used in the code and were therefore removed to improve code readability and maintainability.
